    Title: Photovoltaic device with electrical junction box, method of manufacture and use of the device
    TECHNICAL FIELD OF THE INVENTION The invention relates to a photovoltaic device comprising a photovoltaic module which comprises a plurality of photovoltaic cells arranged side by side on a support layer and interconnected with each other, and an electrical junction box. State of the art
    A photovoltaic module includes a plurality of photovoltaic cells, arranged side by side and interposed between a back support layer and a transparent protective front layer through which the cells can receive light. The cells are interconnected with each other. A group of cells mounted in series form a chain also known by the English name of "string". Several strings can be mounted in parallel in a photovoltaic module. The photovoltaic module is also equipped with a junction box, or external electrical connection, for connecting the photovoltaic module to other photovoltaic modules or to any other external device. This electrical junction box is located at the back of the module. It is connected, at the input, to connectors consisting of ends of electrical tracks connected to the photovoltaic cells and, at the output, to two cables or electrical wires allowing external connection, for example for the series connection of several photovoltaic modules. The junction box also houses an electronic card incorporating security components, such as bypass diodes, for shorting all or part of the photovoltaic cells, especially in the event of shading of one or more of these cells. .
    A known use of photovoltaic modules is to integrate them into roadways paving roads, highways, sidewalks, bike paths, squares or parking.

    For this type of application, it is known to use lightweight photovoltaic modules, flexible, thin (less than 1 cm) and robust vis-à-vis shocks and high loads. The modules are applied on the ground and glued to the floor. A trench or trench must be made in the road to accommodate the junction box and pass the cables under the modules to interconnect. Connectors at the back of the photovoltaic modules, it turns out in practice very difficult for the installer to connect the photovoltaic modules together.

    DETAILED DESCRIPTION OF PARTICULAR EMBODIMENTS OF THE INVENTION
    FIG. 1 diagrammatically shows a photovoltaic device 100, according to one particular embodiment of the invention, in its "ready-to-use" state, at the output of manufacture. The device 100 comprises a photovoltaic module 1 and a junction box 4, or external electrical connection. From the outset, it will be noted that, by definition, the term "before" designates a direction or a side that refers to the face of the photovoltaic module intended to be exposed to light for the production of electrical energy. In contrast, the term "back" refers to a direction or opposite side.
    The photovoltaic module 1 is adapted to be applied, for example by gluing, to a rigid support, such as a roadway, a roof covering or a building facade. It is both flexible and robust. It is for example in accordance with that described in the patent application FR1457275. In this case, it comprises a first transparent front layer intended to receive a luminous flux, two intermediate layers of encapsulation material, respectively upper and lower, a set of photovoltaic cells 2 interposed between the two encapsulation layers, and a rear support layer 3 to be glued on a rigid support, for example a roadway. The photovoltaic cells 2 are arranged side by side on a front face of the support layer 3 and electrically interconnected with each other. For more details on the structure of the photovoltaic module 1, the reader is invited to refer to the patent application FR1457275.
    The photovoltaic module 1 comprises n cells. The cells are arranged in a matrix of x columns and stored there. For example, the module 1 comprises 36 cells arranged in a matrix of 4 columns of 9 cells each. FIG. 1 only shows a head part of the photovoltaic module 1, comprising a first row of four cells 2. The set of photovoltaic cells 2 of the module 1 can be arranged according to several branches or "strings" of cells photovoltaic modules connected in series, the different strings being interconnected in parallel.
    A number N of connection electrical tracks, electrically connected to the cells 2, come out of the photovoltaic module 1. The end portions of these tracks form N electrical strips 11a-11c of the output connection of the photovoltaic module 1 (N being equal to three in Figure 1).
    The support layer 3 is made of a polymer material such as a thermosetting resin for example based on epoxy, or a composite material, for example based on a polymer material and glass fibers. It is both hard and flexible so that it can be fixed, for example by gluing, on a rigid support such as a roadway. It has a rectangular overall shape, here dimensions of 200 cm x 70 cm. The thickness of the support layer 3 is for example 0.5 cm. One of the edges of the support layer 3, which will be called later the mechanical joining edge 30, has a protrusion 31 whose role will be explained later.
    The electrical junction box 4 here has a parallelepiped shape. Referring to Figure 3, it comprises a bottom 40, two longitudinal side walls 41, 42 and two end walls 43, 44, providing an interior space. The housing 4 is open on the top (facing the bottom 40). It is for example made of rigid plastic. By way of illustrative example, the casing 4 has the following dimensions: length 70 cm; - Width 8 cm; - Height (or thickness) less than 5 cm, preferably less than or equal to 3 cm, for example equal to 2 cm.
    The length of the housing 4 is advantageously equal to, or substantially equal to, the length of a mechanical joint edge 30 of the support layer 3. The housing 4 could however be shorter than the mechanical joint edge 30. The interior space of the housing 4 is divided into three compartments 8-10 separated by two inner walls 45, 46: - a first central compartment 8 for receiving an electronic card 5; a second lateral compartment 9 for receiving two connectors 6A and 7A disposed on one side of the first compartment 8; a third lateral receiving compartment 10 of other two connectors 6B and 7B disposed on the other side of the first compartment 8.
    The connectors 6A, 6B, 7A, 7B are external electrical connection connectors. They make it possible to interconnect several photovoltaic modules, here in series, and / or to connect the photovoltaic module 1 to any other external device, by means of electrical connection cables. They comprise here a socket in which one can insert a male connector of an electric cable.
    The bottom 40 of the housing 4 may comprise guiding elements of the electrical connection cables, such as ribs and / or guide pads.
    The electronic card 5 housed in the compartment 8 incorporates security components, and possibly energy conversion components and / or components for monitoring or controlling the electrical characteristics of the photovoltaic modules (current, voltage for example). It also ensures here a return of wiring, or connection, when the photovoltaic module 1 is connected in series with one or more other photovoltaic modules and / or with another external device. With reference to FIG. 5, the card 5 comprises: a first pair of connection terminals 50A-50B, respectively negative (-) and positive (+), interconnected by an electrical track 53 and by a safety circuit, shown schematically by a box 52 in Figure 5, comprising at least one safety component (for example one or more bypass diodes); a second pair of connection terminals 51A-51B, respectively positive (+) and negative (-), directly connected to each other by a conductive electrical track 54 printed on the card 5.
    The conductive track 54 is intended to provide a return connection when several photovoltaic modules (or other external device) are connected in series. This makes it possible to avoid an inductance of mesh, problematic in case of lightning.
    The three electrical strips 11a, 11b and 11c at the output of the photovoltaic module 1 are electrically connected, here by welding, to the safety circuit 52, as shown in FIG. 5. In a known manner, the connection of the electrical strips 11 a-11 c for example, allows a bypass diode to be connected in series on each string of cells 2. In normal operation, the diode is in the off state. If one or more photovoltaic cells of a string are shaded, the diode becomes conductive so as to bypass all the cells of the string. In the embodiment described here, the electrical strips 11a-11c are soldered on the rear face of the electronic card 5, through three slots 47 which are formed in the bottom of the box 4, as shown in FIG.
    The electronic card 5 could integrate other security components, for example a switch to remotely bypass the entire photovoltaic module 1.
    The electronic card 5 is embedded in a material, in this case a resin, ensuring the sealing and the mechanical protection of the card 5.
    The four connectors 6A, 6B, 7A, 7B are sealed. They are respectively connected to the terminals 50A, 51A, 50B and 51B of the electronic card 5, through openings formed through the walls 45, 46 of the compartment 8. Thus, the connectors 6A and 6B are interconnected by the intermediate of the security circuit 52 and the track 53 of the electronic card 5. The connectors 7 A and 7B are directly connected to each other by the electrical track 54. Each connector 6A, 6B, 7A, 7B comprises here a socket in which a male connector of an electrical connection cable can be inserted. The connectors 6A and 6B allow the series connection of the photovoltaic module 1 to one or more other photovoltaic modules and / or device (s) outside (s) via electrical cables (not shown). The connectors 7A and 7B are intended to be connected to electrical cables providing a return wiring when several photovoltaic modules and / or external device (s) are mounted in series.
    When several photovoltaic modules are connected in series, the connectors 6A and 7A, respectively 6B and 7B, of the two modules located at the two ends of the chain of series modules are connected to each other by a connection cable, as shown in Figure 3, to ensure the return of wiring.
    The compartments 9, 10 housing the connectors 6A, 6B, 7A, 7B are open on the top. Thus, the housing 4 is open with respect to the connectors 6A, 6B, 7A, 7B.
    The connection box 4 is secured to the photovoltaic module 1 along the junction edge 30 of the support layer 3 and disposed at the outer periphery of the support layer 3, so that the connectors 6A, 6B, 7A, 7B are accessible. to an operator located at the front of the photovoltaic module 1. The mechanical junction between the housing 4 and the photovoltaic module 1 is here ensured by fixing a longitudinal mechanical junction lip 48 and a rear edge of the support layer 3 , extending along the junction edge 30. The lip 48 is formed by a bearing edge overlying the longitudinal wall 42 of the housing 4. The attachment between the lip 48 and the rear edge of the support layer 3 is for example made by gluing. A seal, for example made of silicone, is interposed between the lip 48 and the rear edge of the support layer 3 in order to seal the mechanical junction between the housing 4 and the photovoltaic module 1. The inner edge of the lip 48 (located towards the inside of the casing 4) can be provided with positioning stops 49 along the compartments 9 and 10. The joining edge 30 of the support layer 3 is intended to bear against these stops 49 This facilitates the relative positioning of the support layer 3 and the housing 4 when they are secured. The protrusion 31 of the support layer 3 along the junction edge 30 constitutes a tongue acting as a closure cap of the compartment 8 housing the electronic card 5. The tongue 31 here has a shape and dimensions adapted to seal the upper compartment opening 8 and support, peripherally, against the upper edges of the side walls of the compartment 8. The tongue 31 is secured to these upper edges, here by gluing and with the interposition of a seal. Thanks to this, the tongue 31 contributes to mechanically reinforcing the mechanical junction between the support layer 3 and the housing 4.
    The electrical strips 11a-11c coming out of the photovoltaic module 1 pass through the support layer 3 through openings 32 formed in the tongue 31. These openings 32 are made in line with slots 80 for the passage of the strips 11a-11c located in the compartment 8, which pass through the latter and open at the rear of the electronic card 5, through the lights 47. With this, the connection strips 11a-11c enter directly into the compartment 8, without undergoing mechanical stress. Slots 80 are however optional.
    Preformed notch zones to be broken are formed in the walls of the casing 4 by a local decrease in the thickness of the wall. They are intended to be broken by an operator or installer, during the installation of the photovoltaic device 100 on site, so as to create notches for the passage of electrical connection cables. In the embodiment described here, two first notch zones are formed in each end wall 43, 44 of the casing 4, so as to make the connecting cables of the casing 4 come out parallel, or substantially parallel, to the edge. junction 30, that is to say in the direction of the length of the housing 4. A second notch zone may be formed in the longitudinal wall 41 of the housing 4 opposite to the joining lip 48, near each end of the housing, so as to output one or more connection cables from the housing perpendicularly, or substantially perpendicularly to the junction edge 30 (that is, perpendicularly, or substantially perpendicularly, in the direction of the length of the housing 4). These second notches are useful for photovoltaic modules located at the beginning or at the end of the chain.
    We will now describe, with reference to Figure 6, the method of manufacturing the photovoltaic device 100 which has just been described, according to a particular embodiment of the invention. This manufacturing process is advantageously carried out before installation on site of the photovoltaic device 100, for example in the factory.
    The method comprises the following steps: E1) to provide the photovoltaic module 1 which comprises, at the front, the plurality of photovoltaic cells 2 arranged on the support layer 3 and interconnected with each other; E2) be provided with the junction box 4 housing the electronic card 5 and the connectors 6A, 6B, 7A, 7B, the housing being initially open with respect to these connectors and the electronic card 5; E3) fasten the housing 4 to the photovoltaic module 1 along a mechanical joint edge 30 of the support layer 3, the housing 4 being disposed at least partially at the outer periphery of the support layer 3 so that the connectors 6A , 6B, 7A, 7B are accessible to an operator located at the front of the photovoltaic module 1.
    During the securing step E3, an operator joins the joining lip 48 of the housing 4 to the rear flange of the support layer 3, extending along the joining edge 30, by making a seal between the lip 48 and the support layer 3. At the same time, the operator closes the compartment 8 receiving the electronic card 5 with the tongue 31. This is also fixed by gluing to the upper edges of the compartment 8 with interposition of a seal.
    After securing the housing 4 and the photovoltaic module 1, during a step E4, the operator passes the ribbons 11a-11c connected to the cells 2 through the openings 32 formed in the tongue 31 to make them penetrate the slots 80 of the compartment 8 and then out of the compartment 8, at the rear of the housing 4, by the lights 47 formed in the bottom 40 of the housing 4. Then it welds the ribbons 11a-11c to the track 53 of the electronic card 5, through the lights 47. It will be noted that in this case, it is the rear face of the electronic card 5 which carries the printed tracks 53, 54 and the security circuit 52. It could be envisaged that these elements are carried by the front face of the electronic card 5 and weld the ribbons 11 a-11c directly on the front face of the card 5 (without emerging at the rear of the housing 4).
    The process is continued by a step E5 of injection of a sealing material, here a thermosetting resin, in the housing 8, through two holes formed in the bottom of the compartment 8.
    In the foregoing description, the photovoltaic module 1 and the junction box 4 are two initially separate elements that are secured to one another to form a one-piece assembly. Alternatively, it could be envisaged that the photovoltaic module 1 and the junction box 4 are made in one piece, the housing being for example molded into the material of the support layer.
    The photovoltaic device 100 can be used to equip a rigid support, for example a roadway, a building facade or a roof. The invention therefore also relates to a roadway equipped with at least one photovoltaic device 100 as previously described. It also relates to a roof or a building facade equipped with at least one photovoltaic device 100 as previously described.
    To install the photovoltaic device 100 in a roadway (or other rigid support), an installer or operator carries out a trench or trench in the roadway (or the rigid support), adapted to receive the housing 4. Then it sticks the rear face of the module photovoltaic 1 on the roadway by placing the housing 4 in the groove. The bonding is carried out in known manner, using a thin adhesive layer which may comprise a special industrial adhesive and / or a bituminous binder. Photovoltaic devices 100 can thus be installed side by side on the roadway. The operator then connects the various devices 100 in series by connecting their respective connectors 6A, 6B, 7A, 7B by son or cables connection. After connecting the photovoltaic devices 100, the operator covers them with a non-opaque coating suitable for the circulation of vehicles and / or pedestrians and mechanically protecting the photovoltaic cells beneath. The term "non-opaque" is intended to mean that the coating is adapted to pass at least a portion of the incident light onto the free surface of the coating, so that the photovoltaic cells beneath receive light. Advantageously, the degree of transparency of the coating is greater than 50%, especially between 50% and 95%. For example, coatings such as those described in the French patent applications filed under the numbers FR 13 51191 and FR 14 57275 may be used. The invention also relates to a use of the photovoltaic device 100 as previously described for equipping a rigid support , in particular a roadway, a building facade or a roof, according to which is carried in the rigid support a receiving groove of the junction box and then the photovoltaic module is applied to the rigid support by placing the housing in the groove. The photovoltaic device, that is to say the photovoltaic module and its junction box, is then covered with a non-opaque coating as previously described.
