    [0001] TECHNICAL FIELD The present invention relates to the field of photovoltaic modules, comprising a set of photovoltaic cells interconnected electrically, and in particular so-called "crystalline" photovoltaic cells, that is to say, the photovoltaic modules. that is, based on silicon crystals or silicon polycrystals.
    [0002] The invention can be implemented for many applications, being particularly concerned by applications that require the use of lightweight photovoltaic modules, flexible and robust against shocks and high mechanical loads. It thus finds a privileged application for its integration on trafficable areas, for pedestrians and / or vehicles, such as roadways or roads, cycle paths, industrial platforms, squares, sidewalks, among others. Such an application is commonly referred to as the "solar road". The invention thus proposes a set of photovoltaic structure comprising a photovoltaic module applied to a circulable zone, the use of such a photovoltaic module for its application over a circulable zone, as well as a method of producing such a set of photovoltaic modules. photovoltaic structure. STATE OF THE PRIOR ART A photovoltaic module is an assembly of photovoltaic cells arranged side by side between a first transparent layer forming a front face of the photovoltaic module and a second layer forming a rear face of the photovoltaic module. The first layer forming the front face of the photovoltaic module is advantageously transparent to allow the photovoltaic cells to receive a luminous flux. It is traditionally made of a single glass plate, having a thickness of about 3 mm. The second layer forming the rear face 3024285 2 of the photovoltaic module can in turn be made from glass, metal or plastic, among others. It is usually formed by a polymeric structure based on an electrically insulating polymer, for example of the polyethylene terephthalate (PET) or polyamide (PA) type, which can be protected by one or more layers based on fluoropolymers, such as polyvinyl fluoride (PVF) or polyvinylidene fluoride (PVDF), and having a thickness of the order of 300 μm. The photovoltaic cells may be electrically connected in series with each other by means of front and rear electrical contact elements, called connection conductors, and formed for example by copper strips, respectively arranged against the front faces (faces facing each other). the front face of the photovoltaic module intended to receive a luminous flux) and rear (faces facing the rear face of the photovoltaic module) of each of the photovoltaic cells. Furthermore, the photovoltaic cells, located between the first and second layers respectively forming the front and rear faces of the photovoltaic module, are encapsulated. In a conventional manner, the encapsulant chosen corresponds to a polymer of the elastomer (or rubber) type, and may for example consist of the use of two layers (or films) of poly (ethylene-vinyl acetate) (EVA) between which the photovoltaic cells and the cell connecting conductors are arranged. Each EVA layer may have a thickness of at least 0.3 mm and a Young's modulus of less than or equal to 30 MPa at room temperature. Usually again, the method for producing the photovoltaic module comprises a single rolling step of the various layers described above, at a temperature greater than or equal to 140 ° C., or even 150 ° C., and for a period of at least 8 minutes, even 15 minutes. After this rolling operation, the two layers of EVA melted to form a single layer in which the photovoltaic cells are embedded. Nevertheless, these known embodiments of the prior art of a photovoltaic module are not entirely satisfactory and have several disadvantages for at least some of their applications.
    [0003] 3024285 3 As part of the application of the solar road type, a need has arisen to use roads or roadways as means of energy production during the day, whether to supply buildings located nearby (businesses, eco-neighborhoods, solar farms, individual houses, among others) or to power the power grid or traffic control devices, for example. Thus, first of all, the presence of a glass plate to form the front face of the photovoltaic module is not compatible with certain applications of the photovoltaic module that may require a relative lightness and ease of formatting of the module. In contrast, prior art designs using glass on the front side of photovoltaic modules involve achieving high module weight and limited integration capability. For an application of the solar road type, the photovoltaic modules with a front face made of glass are, on the one hand, not flexible enough to respond to the deformation of a road, this being of the order of mm every 100 mm for the two horizontal axes, according to the width and the length, of the road. On the other hand, these photovoltaic modules are not sufficiently resistant to static charge if they are glued directly to the roadway. In other words, the roughness of the pavement can cause punching of the photovoltaic cells by the rear face of the photovoltaic module, thus causing risks of breakage of the photovoltaic cells.
    [0004] Solutions have been envisaged for replacing the glass front of photovoltaic modules with plastics while retaining the conventional photovoltaic module architecture and method. By way of examples, patent application FR 2 955 051 A1 and international applications WO 2012/140585 A1 and WO 2011/028513 A2 describe alternatives to glass for designing the front face of photovoltaic modules, among which the use of polymer sheets with a thickness of less than or equal to 500 μm, such as polyvinylidene fluoride (PVDF), ethylene tetrafluoroethylene (ETFE), polymethyl methacrylate (PMMA) or polycarbonate (PC) . However, simply substituting the glass with a polymeric material to obtain a lightweight and flexible photovoltaic module generally results in increased vulnerability of the module to shocks and mechanical loads, unacceptable for certain applications. Furthermore, in these prior art embodiments, the front (glass-free) face of each photovoltaic module is continuous, i.e., it forms a unitary sheet or plate which covers the entire surface of the photovoltaic module. whole module. In this way, the flexibility of each photovoltaic module can be limited and above all not sufficient. Moreover, this also poses a problem of accentuation of differential expansion stresses between the different layers of the structure, which can lead to undesirable deformations or detachments at the interfaces of the structure, such as for example at the encapsulant / layer interface external. Some solutions have been proposed to obtain a relative discontinuity of the front face of a photovoltaic module in order to obtain a better flexibility of the module and to better manage the differential expansion stresses. Thus, for example, US patent application 2014/0000683 A1 discloses a method for encapsulating photovoltaic cells individually. The encapsulated cells can then be interconnected to obtain a flexible photovoltaic module. Furthermore, the patent application US 2014/0030841 A1 teaches the implementation of a photovoltaic module on a flexible substrate. The photovoltaic module is composed of "submodules" consisting of interconnected photovoltaic cells, each sub-module being electrically independent of neighboring submodules. However, the solutions described above are not totally satisfactory in terms of flexibility, resistance to shocks and mechanical loads, performance and cost of photovoltaic modules, in particular for constraining applications that require them strongly at the same time. of their mechanical resistance. DISCLOSURE OF THE INVENTION There is thus a need to propose an alternative solution for designing an assembly provided with a photovoltaic module applied to a circulable zone to meet at least some of the constraints inherent to the applications targeted by the use of the photovoltaic module, in particular to improve the flexibility, the rigidity, the lightness and the resistance to shocks and mechanical loads of the photovoltaic module. In particular, there is a need to further improve the photovoltaic modules intended to be integrated in circulating areas, for pedestrians and / or vehicles, for example to increase their resistance to the load induced by the passage of a vehicle while presenting a some flexibility. The object of the invention is to remedy at least partially the needs mentioned above and the drawbacks relating to the embodiments of the prior art. The invention thus has, according to one of its aspects, a set of photovoltaic structure, comprising: a circulable zone, a photovoltaic module applied to the circulable zone, the photovoltaic module comprising at least: a first transparent layer forming the front face of the photovoltaic module intended to receive a luminous flux, - an assembly of a plurality of photovoltaic cells arranged side by side and electrically connected to one another, - an assembly encapsulating the plurality of photovoltaic cells, - a second layer forming the rear face of the photovoltaic module, intended in particular to be secured to a circulable zone, the encapsulating assembly and the set of a plurality of photovoltaic cells being located between the first and second layers, and - a layer of fixing, consisting in particular of a bituminous adhesive, situated between the circulable zone and the photovoltaic module allowing the adhesion of the photovoltaic module to the circulable zone, characterized in that the first layer consists of at least one transparent polymeric material and has a plurality of plates independent of each other, each plate being located opposite at least one photovoltaic cell, so as to form a discontinuous front face of the photovoltaic module, and in that the rigidity of the encapsulating assembly is defined by a Young's modulus of the encapsulation material greater than or equal to 75 MPa at room temperature and a thickness of the layer between 0.4 and 1 mm. Initially, that is to say before any rolling operation, the encapsulant assembly consists of two layers of encapsulation material, called core layers, between which the set of a plurality of photovoltaic cells is encapsulated. . However, after the layer rolling operation, the layers of encapsulation material have melted to form a single layer (or assembly) in which the photovoltaic cells are embedded. Prior to any rolling operation, each layer of encapsulation material may thus have a modulus defined by a Young's modulus of encapsulation material greater than or equal to 75 MPa at room temperature and a thickness of the layer between 0.2. and 1 mm, or even between 0.2 and 0.5 mm. The assembly encapsulating the plurality of photovoltaic cells thus consists of the two layers of encapsulation material, namely the layers of encapsulation material which before rolling are in direct contact with the photovoltaic cells. The term "transparent" means that the material of the first layer forming the front face of the photovoltaic module is at least partially transparent to visible light, allowing at least about 80% of that light to pass through. In addition, by the expression "plates independent of each other" is meant that the plates are located at a distance from one another, each forming a unitary element independent of the first layer and from each other, superimposed on at least one a photovoltaic cell. The assembly of all these plates then forms the first layer with a discontinuous appearance. In addition, by the term "encapsulant" or "encapsulated", it should be understood that the set of a plurality of photovoltaic cells is arranged in a volume, for example hermetically sealed, at least partially formed by the layers of encapsulation, joined together after rolling.
    [0005] Moreover, the term "circulating zone" designates any zone intended for the circulation of pedestrians and / vehicles, such as, for example, a road (or road), a motorway, a cycle path, an industrial platform, a square , a sidewalk, this list being in no way limiting.
    [0006] In addition, the term "room temperature" means a temperature of between about 15 and 30 ° C. Thanks to the invention, it may thus be possible to provide an alternative solution for the design of a photovoltaic structure assembly comprising a flexible and relatively flexible photovoltaic module, and also sufficiently robust to resist shocks and mechanical loads. suffered, especially after application on the circulable area. In particular, the use of a discontinuous front face can give the photovoltaic module a flexible character, in particular to facilitate its application on a non-planar support, for example curved. In addition, the use of a high rigidity encapsulation material on either side of the photovoltaic cells can make it possible to adequately protect the photovoltaic cells against the risk of a high mechanical load or shock, in particular limiting their flexion, and thus limiting the risk of breakage. In addition, the lack of use of a glass material for the front face of the photovoltaic module may allow the photovoltaic module to have a weight less than that of a photovoltaic module according to the prior art, typically from order of 12kg / m2, depending on the thickness of the different layers used. Finally, the use of a discontinuous front face made of a polymer material may make it possible to guard against problems of thermal expansion during the use of the photovoltaic module outdoors. Indeed, the thermal expansion being proportional to the dimensions of the first layer 25 forming the front face of the module, the fact of using plates having dimensions close to those of the photovoltaic cells can significantly limit the displacements induced by thermal stresses. which may give rise to delamination or uncontrolled conformation of the photovoltaic module.
    [0007] The photovoltaic structure assembly according to the invention may further comprise one or more of the following characteristics taken separately or according to any possible technical combinations. The second layer forming the rear face of the photovoltaic module may also be discontinuous. In other words, the second layer may also include a plurality of plates independent of each other, each plate being located facing, that is to say superimposed, at least one photovoltaic cell. The presence of a discontinuous rear face on the photovoltaic module may for example make it possible to further improve the flexibility of the module to facilitate its application on a circulable zone provided with a surface roughness. Moreover, even though the first layer forming the front face of the photovoltaic module, and possibly the second layer forming the rear face of the module, have a discontinuous appearance, the set of a plurality of photovoltaic cells and the encapsulating assembly are advantageously continuous.
    [0008] According to one particular embodiment of the invention, each plate of the first layer, and possibly of the second layer, may be located opposite several photovoltaic cells. This may especially be the case for photovoltaic cells of smaller dimensions than those of conventional photovoltaic cells, typically 156 x 156 mm.
    [0009] In addition, when a single photovoltaic cell is located opposite each plate of the first layer, and possibly of the second layer, each plate may have dimensions at least equal to those of the photovoltaic cell to which it is superimposed. The photovoltaic module is advantageously devoid of a first layer forming the front face of the module made of glass. Thus, as indicated above, it may be possible to improve the lightness and the integration capacity of the photovoltaic module. The encapsulation material forming the two layers of core encapsulation material of the encapsulant assembly may have a Young's modulus at room temperature greater than or equal to 100 MPa, in particular greater than or equal to 150 MPa, or even 200 MPa. . It is in particular 220 MPa. The encapsulant assembly may be formed from two layers of encapsulating material having the same or different thicknesses.
    [0010] The second layer forming the rear face of the photovoltaic module may consist preferably of at least one composite material, in particular of the polymer / glass fiber type. The second layer preferably also has a coefficient of thermal expansion less than or equal to 20 ppm, and preferably less than or equal to 10 ppm.
    [0011] The second layer forming the rear face of the photovoltaic module may or may not be transparent. The rigidity of the second layer forming the rear face of the photovoltaic module can be defined by a stiffness factor corresponding to the Young's modulus at room temperature of the material of the second layer multiplied by the thickness of the second layer, lying between and 15 GPa.mm. In addition, the rigidity of the second layer forming the rear face of the photovoltaic module can be defined by a Young's modulus at room temperature of the material of the second layer greater than or equal to 1 GPa, better still or equal to 3 GPa, even better greater than or equal to 10 GPa, and a thickness of the second layer 20 between 0.2 and 3 mm. In this way, the second layer forming the rear face of the photovoltaic module can have a high rigidity, which can thus limit its flexibility. However, this high rigidity can make it possible to reduce or even prevent punching of the photovoltaic cells by the rear face of the module, that is to say the appearance of cracks and / or breaks in the photovoltaic cells, when it is applied on a support having a large surface roughness. The spacing between two adjacent photovoltaic cells, or consecutive or adjacent cells, may be greater than or equal to 1 mm, in particular between 1 and 30 mm, and preferably greater than or equal to 3 mm, in particular between 10 and 20 mm .
    [0012] The two neighboring photovoltaic cells considered may be two neighboring cells of the same series (also referred to as "string" in English) or two neighboring cells respectively belonging to two consecutive series of the set of photovoltaic cells.
    [0013] The presence of a large spacing between the photovoltaic cells can make it possible to obtain an equally important spacing between the plates of the first layer forming the front face of the photovoltaic module. In this way, the discontinuous appearance of the front face of the module is accentuated, thus allowing to give flexibility to the module to facilitate its application on the circulable area.
    [0014] Advantageously, the spacing between two adjacent plates of the first layer, and possibly of the second layer, is less than or equal to the spacing between two neighboring photovoltaic cells. The module may also preferably comprise an intermediate layer called "damping" layer located between the first layer forming the front face 15 of the photovoltaic module and the assembly encapsulating the plurality of photovoltaic cells, allowing assembly, particularly by gluing, of the first layer on the encapsulating set. The intermediate layer may consist of at least one polymeric material, in particular a thermoplastic or thermosetting polymer resin.
    [0015] The intermediate layer may be, for example, in sheet form or in liquid form. It can be adhesive, for example of the PSA type, or not. It can be carried out hot or at room temperature. The rigidity of the intermediate layer can be defined by a Young's modulus of the intermediate layer material of 50 MPa or less at room temperature and a thickness of the intermediate layer of between 0.01 and 1 mm. The intermediate layer can in particular fulfill two main functions. On the one hand, it can allow the adhesion of the first layer forming the front face of the photovoltaic module on the encapsulating assembly for the case where the two layers are not chemically compatible. On the other hand, it can create within the 3024285 11 photovoltaic module a "damping" layer of flexibility to improve the impact resistance and mechanical loads of the module. This intermediate layer may be optional, in particular absent when there is chemical compatibility between the first layer forming the front face of the photovoltaic module and the encapsulating assembly. The photovoltaic module may further comprise an adhesive layer located between the second layer forming the rear face of the photovoltaic module and the assembly encapsulating the plurality of photovoltaic cells, allowing the assembly, particularly by bonding, of the second layer on the whole. encapsulant.
    [0016] By "adhesive layer" is meant a layer allowing, once the photovoltaic module is made, the second layer to adhere to the encapsulating assembly. It is thus a layer for chemical compatibility and adhesion between the encapsulant and the back side, and the thickness of the first layer forming the front face of the photovoltaic module can be greater than or equal to 0 , 1 mm, in particular between 0.5 and 6 mm, the circulable zone may have a surface roughness, and, as indicated above, the assembly comprises a fixing layer, in particular by bonding, situated between the circulating zone and the photovoltaic module The use of the fixing layer can make it possible to obtain a rear face of the reinforced photovoltaic module, making it possible to avoid the risk of punching of the photovoltaic cells by the rear face when the circulable zone has a surface roughness. the photovoltaic module is subjected to a shock or a high mechanical load, because the interface between the rear face of the module and the zone As a result, a valuable binder can be filled. The fixing layer may comprise an adhesive, for example an epoxy or polyurethane glue, among others. It may in particular comprise a special industrial adhesive.
    [0017] The fixing layer may also comprise a bituminous binder, optionally reinforced by adding a polymer such as Styrene-Butadiene-Styrene (SBS), hot or emulsion. In one embodiment, the fixing layer is directly spread over the surface of the circulating zone, spread out in a thin layer, then the photovoltaic module is deposited therein while the adhesive has not hardened or the bituminous binder is still viscous and tights. In addition, the assembly may comprise a coating layer, in particular allowing the passage of pedestrians and / or vehicles, applied to the first layer 10 forming the front face of the photovoltaic module, the coating layer being non-opaque and presenting a surface textured and irregular outer surface, in particular a macrotextured and irregular microtextured outer surface, with an average texture depth PMT measured according to the NF EN 13036-1 standard of between 0.2 mm and 3 mm and a PSV value (for "Polished Stone Value In English) according to standard 15 NF EN 13043 of at least PSV44, better PSV50, even better PSV53. The coating layer may advantageously have an outer surface reproducing the texture of a road surface coating and circulable. By the term "irregularly" it is meant that the reliefs giving macrotexture and microtexture to the coating layer are not all of the same shape or size. These reliefs can be obtained from texturing elements having not the same shape or size, being uncalibrated. The coating layer advantageously has a degree of transparency greater than 50%, for example between 50 and 95%, in a range of 100 nm around the peak efficiency of the photovoltaic cells, especially in the range 500-700 nm. The average texture depth PMT of the coating layer may be at least 0.30 mm, more preferably at least 0.6 mm. In addition, the coating layer may comprise a non-opaque matrix, preferably Young's modulus at room temperature between 0.1 and 10 GPa.
    [0018] The matrix may be chosen from materials of synthetic or vegetable origin, bituminous binders, preferably of penetrability class according to the standard EN 1426 160/220, 100/150, 70/100, 50/70, 40 / 60, 35/50, 30/45 or 20/30 (in tenths of a millimeter), road binders clear synthetic or plant origin, preferably of penetrability class according to EN 1426 160/220, 100 / 150, 70/100, 50/70, 40/60, 35/50, 30/45 or 20/30 (tenth of a millimeter) and the polymeric binders. The texture of the outer surface of the coating layer may be defined at least partially by non-opaque texturing elements, preferably of irregular shape, better random. The texturizing elements may be arranged in a monolayer, preferably pressed about halfway into the matrix of the coating layer. These texturing elements may be chosen from aggregates of transparent or translucent materials, organic or inorganic, especially polycarbonate or glass. They may have a size ranging from 0.1 mm to 10 mm, better from 0.4 to 4 mm, and still more preferably from 0.9 to 1.4 mm. The coating layer may for example be a binder of the bituminous type as defined in standard NF EN 12591, such as the Bituclair binder marketed by Colas. The coating layer may also be a clear synthetic road binder or plant origin, such as binders Vegecol or Vegeclair marketed by the company Colas.
    [0019] The coating layer may also be a binder of a purely synthetic nature or of vegetable origin, the binder preferably being organic in nature, preferably of a polymeric nature, such as an acrylic, epoxy or polyurethane resin, such as the so-called epoxy varnishes. Varnishes D marketed by the company Résipoly, or a polyurethane Sovermol marketed by the company BASF.
    [0020] In addition, the invention also relates, in another of its aspects, to the use, for its application on a circulable zone, in particular a roadway, of a photovoltaic module comprising at least: a first transparent layer forming the front face of the photovoltaic module intended to receive a luminous flux, an assembly of a plurality of photovoltaic cells arranged side by side and electrically connected to one another, an assembly encapsulating the plurality of photovoltaic cells, a second layer forming the rear face of the photovoltaic module, the encapsulant assembly and all of a plurality of photovoltaic cells being located between the first and second layers, the first layer consisting of at least one transparent polymeric material and having a plurality of plates independent of each other, each plate being located opposite at least one photovoltaic cell that so as to form a discontinuous front face 10 of the photovoltaic module, and the rigidity of the encapsulant assembly being defined by a Young's modulus of the encapsulation material greater than or equal to 75 MPa at room temperature and a thickness of the encapsulant assembly between 0.4 and 1 mm, the photovoltaic module being applied to the circulable zone via a fixing layer, consisting in particular of a bituminous adhesive. Moreover, another aspect of the invention is a method for producing a photovoltaic structure assembly as defined above, comprising at least the following four successive stages of: a) hot rolling at a temperature above 150 ° C of all the constituent layers of the photovoltaic module except the first layer forming the front face of the photovoltaic module and a possible intermediate layer called "damping", located between the first layer and the assembly encapsulating the plurality of photovoltaic cells, b) rolling at a temperature of less than or equal to 150 ° C, more preferably 125 ° C, for example at room temperature, the first layer forming the front face of the photovoltaic module, and any intermediate layer , on the constituent layers of the photovoltaic module laminated together during the first step a), c) application of a layer of e coating on the first layer forming the front face of the photovoltaic module, in particular to allow the passage of pedestrians and / or vehicles, the coating layer being non-opaque and having a textured outer surface and irregular, including an outer surface macrotextured and microtextured irregularly, with a mean texture depth PMT measured according to the NF EN 13036-1 standard between 0.2 mm and 3 mm and a value of PSV 5 (for "Polished Stone Value" in English) according to the NF standard EN 13043 of at least PSV44, better PSV50, even better PSV53, d) fixing the photovoltaic module on a circulatory zone to form the photovoltaic structure assembly, by means of a fixing layer of the photovoltaic structure assembly, consisting in particular of an asphalt adhesive.
    [0021] In the first rolling step a), the constitutive layers of the photovoltaic module concerned are thus the set of a plurality of photovoltaic cells, the encapsulating assembly and the second layer forming the rear face of the photovoltaic module. In addition, prior to the implementation of the second step b), the plates of the first layer may advantageously be treated with Corona treatment equipment so as to obtain a surface energy greater than or equal to 48. dyn / cm. The optional intermediate layer called "damping" may facilitate the bonding of the first layer forming the front face of the module on the other 20 layers. This intermediate layer is optional. In particular, it may not be necessary when there is a chemical compatibility between the first layer forming the front face of the module and the encapsulating assembly. As indicated above, the thickness of the encapsulating assembly may be between 0.4 and 1 mm, the latter resulting from the rolling association of at least two layers of encapsulation material each having a thickness of between 0.2 and 0.5 mm. These two layers of encapsulating material may also have different thicknesses. Advantageously, the implementation of at least two rolling steps in the process according to the invention for producing the photovoltaic module can make it possible to overcome any thermal expansion problems that may arise due to the use of a front face of the module made of a polymer material. Indeed, some layers of the photovoltaic module need to be laminated at a temperature greater than or equal to 140 ° C., or even 150 ° C., but rolling at this temperature level in a single step, in accordance with the practice according to US Pat. prior art, all the layers of the module, including that forming the front face of the module, can give rise to an uncontrolled conformation and to significant delaminations of the front face of the photovoltaic module because of excessive mechanical stresses generated .
    [0022] Also, the presence of at least a second rolling step at a lower temperature than for the first step, for rolling the front face of the photovoltaic module, possibly combined with the presence of an intermediate layer called "damping" allowing bonding the front face of the module to the encapsulating material and damping the thermal stresses, may make it possible to limit or even prevent thermal expansion. Alternatively, the invention also relates, in another of its aspects, to a method of producing a photovoltaic structure assembly as defined above, comprising at least the following three successive stages of: a) hot rolling at a temperature greater than or equal to 150 ° C of all the constituent layers of the photovoltaic module, b) application of a coating layer on the first layer forming the front face of the photovoltaic module, in particular to allow the passage of pedestrians and / or vehicles, the coating layer being non-opaque and having a textured and irregular outer surface, in particular an irregularly microtextured and macrotextured outer surface, with an average texture depth PMT measured according to the NF EN 13036-1 standard of between 0, 2 mm and 3 mm and a value of PSV (for "Polished Stone Value" in English) according to standard NF EN 13043 of at least PSV44, mi PSV50, even better PSV53, 3024285 17 c) fixing the photovoltaic module on a circulable zone to form the photovoltaic structure assembly, by means of a fixing layer of the photovoltaic structure assembly, consisting in particular of a bituminous adhesive . The photovoltaic structure assembly and the method according to the invention may comprise any of the previously mentioned features, taken alone or in any technically possible combination with other features. BRIEF DESCRIPTION OF THE DRAWING The invention will be better understood on reading the detailed description which follows, of an example of non-limiting implementation thereof, as well as the examination of the single figure, schematic and partial, of the accompanying drawing, illustrating, in section and in exploded view, an embodiment of a photovoltaic structure assembly according to the invention. In this single figure, the different parts shown are not necessarily in a uniform scale, to make the figure more readable. DETAILED DESCRIPTION OF A PARTICULAR EMBODIMENT Reference is made here to FIG. 1, illustrating in cross section and in exploded view an exemplary embodiment of a photovoltaic structure assembly 10 according to the invention.
    [0023] It should be noted that FIG. 1 corresponds to an exploded view of the photovoltaic structure assembly 10 before the rolling steps of the method according to the invention. Once the rolling steps have been performed, the different layers are in fact superimposed on each other, but also a little deformed so that at least the plates 8 of the first layer 3 sink into the assembly formed by the layer intermediate 9 and 25 encapsulating assembly 6a, 6b which deform. The rolling steps provide hot and vacuum pressing. Depending on the thicknesses of the different layers, the plates 8 may or may not be flush with the photovoltaic module 1, the material of the intermediate layer 9 and possibly that of the encapsulating assembly 6a, 6b may also fill at least a portion of the 8. As previously explained, the photovoltaic module 1 according to the invention is designed to be sufficiently flexible in order to be able to apply it, in particular by gluing, to a circulating zone 2, in particular a roadway, which can present a surface roughness, in other words not necessarily flat and smooth. In addition, the photovoltaic module 1 according to the invention is also designed to withstand static or dynamic pressures of up to 1500 kN / m2 or 5000 kN / m2. The circulating zone 2 is advantageously sufficiently rigid not to deform when the same stress is applied as that applied to the photovoltaic module 1. As can thus be seen in FIG. 1, the photovoltaic module 1 comprises a first layer 3 forming the front face of the module 1 for receiving a luminous flux, an encapsulating assembly 6a, 6b, obtained by the fusion of two layers of upper encapsulation material 6a and lower 6b, a set 4 of photovoltaic cells 5 taken between two layers of upper encapsulation material 6a and lower 6b, and a second layer 7 forming the rear face of the photovoltaic module 1 intended to be bonded to the circulating zone 2. The two layers of encapsulation material 6a and 6b forming the encapsulating assembly, as well as any intermediate layer 9 described later, form a relatively flexible structure that can be realized from a single material or multiple materials in the event of chemical incompatibility. According to the invention, the first layer 3 is made of a transparent polymer material and comprises a plurality of plates 8 independent of each other, each plate 8 being located opposite a photovoltaic cell 5, so as to form a discontinuous front face of the photovoltaic module 1. The transparent polymer material of the first layer 3 can for example be chosen from polycarbonate (PC), polymethyl methacrylate (PMMA), ethylene tetrafluoroethylene (ETFE), or polyfluoride vinylidene (PVDF), among others. In addition, the thickness of the first layer 3 may be greater than 0.1 mm, and ideally between 0.5 and 6 mm. In this example, the first layer 3 thus consists of several plates 8, of dimensions equal to 162 x 162 mm, PMMA of thickness equal to 3 mm. On the other hand, the photovoltaic cells 5 are electrically interconnected with each other with a spacing s between two neighboring cells equal to about 15 mm. The photovoltaic cells 5 may be so-called "crystalline" cells, that is to say based on silicon crystals or silicon polycrystals, with a homojunction or heterojunction, and with a thickness of less than or equal to 250 μm. Moreover, in this example, each plate 8 extends in superposition on each side of the underlying photovoltaic cell 5 over a distance of about 3 mm, so that the spacing between two adjacent plates 8 here is equal to the spacing s between two neighboring cells decreased by about 2 times 3 mm, or about 6 mm. In addition, the rigidity of each encapsulation material layer 6a and 6b is defined by a Young's modulus E at ambient temperature of the encapsulation material greater than or equal to 50 MPa, or even 75 MPa, or even 100 MPa, of preferably greater than or equal to 200 MPa, and a thickness e of the layer 6a, 6b between 0.2 and 1 mm. The encapsulation material layers 6a and 6b form an encapsulating assembly preferably chosen to be an ionomer such as the ionomer sold under the name of jurasol® ionomer DG3 by the company Jura-plant or the ionomer sold under the name of PV5414 by Du Pont, having a Young's modulus at room temperature greater than or equal to 200 MPa and a thickness of about 500 μm. The second layer 7 forming the rear face of the photovoltaic module 1 is constituted by a polymeric material such as thermosetting resins such as epoxy resins, transparent or not, or a composite material, for example of the polymer / fiber type. of glass. In this example, the second layer 7 consists of a composite material of the polymer / glass fiber type, in particular a polypropylene-based fabric and glass fiber with a glass fiber content of 60 to 30% by weight, such as Thermopreg® fabric P-WRt-1490-PP6OW sold by the company Owens Corning Vetrotex, having a thickness of about 1 mm and a Young's modulus at room temperature of about 12 GPa. Furthermore, an adhesive layer 11, or compatibilizing (its presence being justified in the case of chemical incompatibility), is located between the second layer 7 5 forming the rear face of the photovoltaic module 1 and the encapsulating assembly formed by the two layers encapsulation material 6a and 6b on either side of the assembly 4 of photovoltaic cells 5. This adhesive or compatibilizing layer 11 allows the bonding of the second layer 7 on the layer of lower encapsulation material 6b. In the case of using the Thermopreg® fabric P-WRt-1490-PP6OW for the second layer 7, the compatibilizing layer 11 is preferably chosen to be a Mondi TK41001 type film having a thickness of about 50 μm. In addition, as can be seen in FIG. 1, the photovoltaic module 1 also comprises an intermediate layer 9 called "damping layer" located between the first layer 3 and the encapsulating assembly formed by the two layers of encapsulation material 6a. and 6b on either side of the set 4 of photovoltaic cells 5. The intermediate layer 9 allows the bonding of the first layer 3 to the layer of upper encapsulation material 6a. The intermediate layer 9 is for example constituted by a standard encapsulant used in the field of photovoltaics, such as the ethylene-vinyl acetate (EVA) copolymer, a polyolefin, silicone, thermoplastic polyurethane, polyvinyl butyral , among others. It can also be constituted by a liquid resin of the acrylic type, silicone or polyurethane, monocomponent or two-component, crosslinkable hot or photochemically. It can also be constituted by a pressure-sensitive adhesive of the PSA type (for "Pressure-Sensitive Adhesive" in English). In this example, the intermediate layer 9 is constituted by a thermoplastic film, namely thermoplastic polyurethane also known by the acronym TPU, such as TPU TPU Dureflex® A4700 sold by the company Bayer or PX1001 marketed by American Polyfilm, 30 of thickness equal to about 380 μm.
    [0024] The intermediate layer 9 serves to fulfill two main functions. On the one hand, it allows the adhesion of the first layer 3 to the upper encapsulation material layer 6a for the case where the two layers are not chemically compatible. On the other hand, it allows to create within the photovoltaic module 1 5 a "damping" layer of a certain flexibility to improve the impact resistance and mechanical loads of the module 1. Moreover, the assembly 10 of Photovoltaic structure according to the invention shown in Figure 1 also comprises a circulable zone 2. The circulable zone 2 may be of variable rigidity. In this example, it particularly corresponds to a paved surface of the pavement type. In order to allow the gluing of the photovoltaic module 1 to the circulating zone 2, the assembly 10 also comprises a fixing layer 12. This attachment layer 12 is constituted by a bituminous glue for adhering the module 1 to the roadway or road . In this example, it is a bitumen of the ColFlex N type marketed by the company Colas, with a dosage of 1 kg / m2. The use of a bituminous adhesive 12 associated with a rear face 7 of the module 1 made of a composite material can make it possible to reinforce the rear face 7 so as to avoid the risk of puncturing the photovoltaic cells 5 subjected to the passage of pedestrians and / or of vehicles on a 2 rough roadway. Asphalt adhesive 12 thus acts as a protective binder 20 filling the interface between the floor 2 and the rear face 7 of the module 1. In addition, although not shown in Figure 1, the assembly 10 of structure photovoltaic also comprises a layer of coating applied to the first layer 3, intended to facilitate the movement of pedestrians and / or vehicles. The coating layer is non-opaque and has a textured and irregular outer surface, in particular an irregularly microtextured, macrotextured outer surface, with an average texture depth PMT measured according to the NF EN 13036-1 standard of between 0.2 mm and 3 mm. mm and a PSV value according to the NF EN 13043 standard of at least PSV44, or even PSV50, or even PSV53. A method of making a photovoltaic structure assembly 10 according to the invention will now be described.
    [0025] The method comprises a first step a) of hot rolling at a temperature of about 170 ° C and under vacuum (pressure less than or equal to 10 mbar) of the constituent layers 6a, 4, 6b, 11 and 7 of the photovoltaic module. 1 except for the first layer 3 and the intermediate layer 9. This first rolling step a) is carried out for about 15 minutes so as to obtain a "laminate" of encapsulated photovoltaic cells. The rolling parameters, such as temperature, time and pressure, may however depend on the encapsulant material used. Then, the method comprises a second step b) of hot rolling at a temperature of about 125 ° C. and under vacuum of the "laminate" obtained during the first step a) with the first layer 3 forming the front face of the photovoltaic module 1 using the intermediate layer 9. This second step b) is performed for a period of about 30 minutes so as to obtain the photovoltaic module 1. Before the implementation of this second step b), the Plates 8 of the first layer 3 may advantageously be treated with Corona treatment equipment so as to obtain a surface energy greater than or equal to 48 dyn / cm. These first a) and second b) rolling steps are then followed by a step c) of applying a coating layer on the first layer 3 to allow the passage of pedestrians and / or vehicles, the coating layer being as previously described. Finally, a fixing step d) of the photovoltaic module 1 20 on the circulating zone 2 makes it possible to form the photovoltaic structure assembly 10. This fixing step is advantageously carried out using an asphalt adhesive applied between the circulating zone 2 and the module 1. Tests have been carried out with various photovoltaic modules 1, comprising from 3 to 40 photovoltaic cells 5, according to the method described above. The resistance to the mechanical load of these modules 1, bonded to a road mix 2, with pressures of up to 500 kN / m 2 in static and dynamic conditions, has been demonstrated. For example, a photovoltaic module 1, consisting of three photovoltaic cells 5, has not undergone any degradation after about 64,000 applications with a pressure of 500 kN / m 2.
    [0026] Therefore, the photovoltaic module 1 may have an increased mechanical resistance adapted to demanding applications in terms of mechanical stresses, such as the type of the solar road, but also have a piecewise flexibility due to the presence of a face before 3 discontinuous, allowing it to take 5 different forms to adapt to different types of surfaces, for example rough or imperfect flatness. In addition, the presence of a reinforced rear face 7 can make it possible to improve the punching resistance of this rear face 7 of the module 1, this punching being able to result from the roughness of the support 2 on which the module 1 is applied and which can lead to cracks photovoltaic cells 5 10 photovoltaic module 1. Of course, the invention is not limited to the embodiment which has just been described. Various modifications may be made by the skilled person. The expression "having one" shall be understood as being synonymous with "having at least one", unless the opposite is specified. 15
