    METHOD FOR MANUFACTURING PREFABRICATED CONSTRUCTION ELEMENT
    AND PHOTOVOLTAIC
    The present invention relates to the technical field of the production of electricity from renewable energies, in particular solar energy, thanks to the photovoltaic effect.
    More specifically, the present invention relates to a method for manufacturing a prefabricated element intended for construction and comprising at least one photovoltaic module intended to produce electricity.
    The energy crisis and environmental considerations are driving manufacturers to find energy-efficient and environmentally friendly solutions. Photovoltaic solutions can contribute to this effort by providing innovative solutions in many areas, including the technical field of concrete.
    Indeed, cities include many buildings, buildings, structures or infrastructure (including transport) made of concrete and offering large surface capacities that would be relevant to use to produce electricity from solar energy.
    It is known to install photovoltaic panels on concrete surfaces subsequent to the construction of these surfaces.
    However, such installations require the installation of a load-bearing structure which sometimes requires certain adaptations to conform to the concrete surface on which the photovoltaic panels are intended to be installed.
    In addition, such an installation requires the use of a specialized workforce.
    Thus, it appears interesting to use the concrete surfaces available in the cities and that from the moment of their construction so as to limit the subsequent use of additional resources.
    The patent application FR14 / 55388 describes a method of manufacturing a prefabricated concrete element for the realization of buildings, buildings, structures or infrastructure and able to produce electricity.
    This prefabricated element comprises a photovoltaic thin film deposited on one of these surfaces, which does not require the use of a carrier structure to manufacture a photovoltaic panel from a plurality of these elements.
    Such a process consists in coating the surface of a hardened concrete with a polymer film obtained by polymerization under the action of radiation, then depositing a thin photovoltaic layer on this polymer film using techniques whose basic principle This consists of depositing or condensing the thin layer-forming overlay material under partial vacuum, for example, using a pressure of 10-2 to 10-4 Torr, while the support material is heated to a constant temperature.
    This method is satisfactory as regards the adhesion of the photovoltaic thin film to the surface of the concrete element. Nevertheless, such a process requires the implementation of complex techniques that are difficult to control during mass production on an industrial scale.
    The present invention aims to solve all or part of the problems described above.
    Also, the technical problem to be solved by the present invention is to simplify the manufacturing process of a prefabricated element intended for construction and comprising a photovoltaic module for producing electricity.
    For this purpose, the present invention relates to a method for manufacturing a prefabricated element intended for the construction and production of electricity comprising the following steps: - having at least one photovoltaic module, said at least one module photovoltaic having a front face intended to be oriented towards a light source and a rear face opposite the front face, - to have a formwork mold, - to introduce the at least one photovoltaic module into the formwork mold, for that: positioning the at least one photovoltaic module against one of the walls of the formwork mold, the front face of the at least one photovoltaic module being disposed opposite said wall, and / or replacing one of the walls of the formwork mold by all or part of the at least one photovoltaic module, the front face of the at least one photovoltaic module being arranged facing an area of the space located at the the outside of the mold, - depositing a structural adhesive material or a mixture of structural adhesive materials on all or part of the rear face of the at least one photovoltaic module disposed facing an area of the space located inside the mold, - pour a fresh concrete into the formwork mold so as to cover the structural adhesive material.
    A prefabricated element intended for the construction according to the present invention can be any element or part of an element of a construction such as for example a foundation, a base, a wall, a beam, a pillar, a bridge stack, a blockwork , a block, a pole, a staircase, a panel, including a facade panel, a cornice, a tile or a roof terrace. However, such a prefabricated element is also intended for the production of electricity and must therefore be exposed to a light source, especially in the sun.
    Unexpectedly, the inventors have demonstrated that it is possible to properly adhere a photovoltaic module on fresh concrete by using a structural adhesive material which, unlike a prejudice, does not lose its adhesion due to its use. with fresh concrete.
    This method considerably simplifies the manufacture of prefabricated concrete elements comprising a photovoltaic module.
    Indeed, the placement and bonding of the photovoltaic module directly in contact with the formwork mold allows a very appreciable time saving, typically less than a day compared to gluing or rolling steps of a photovoltaic module on concrete already hardened typically requiring several days.
    In addition, this method abstains from any problem of water degassing and makes it easier to mold the shape and dimensions of concrete panels, while easily providing the space required for the output of the electrical connectors.
    According to one implementation of the method, the at least one photovoltaic module is positioned horizontally against one of the walls of the formwork mold, in particular the bottom wall of the formwork mold.
    This arrangement makes it possible to transfer to one of the walls of the more resistant formwork mold all or part of the force exerted by the fresh concrete on the at least one photovoltaic module, which preserves the photovoltaic module.
    According to one implementation of the method, the at least one photovoltaic module is positioned vertically against one of the walls of the formwork mold, in particular a side wall of the formwork mold.
    This arrangement makes it possible to envisage a prefabricated element comprising several photovoltaic modules arranged on different sides of the element.
    According to one implementation of the method, the method further comprises a prior sandblasting step of the rear face of the at least one photovoltaic module.
    This arrangement makes it possible to increase the specific surface area of the rear face of the at least one photovoltaic module and therefore to increase the adhesion of the structural adhesive material.
    According to one implementation of the method, the structural adhesive material is applied by spraying, using a roller or with the aid of a brush.
    This arrangement simplifies the application of the structural adhesive material.
    According to one implementation of the method, the structural adhesive material comprises at least one polymer, for example from the family of epoxides, polyurethanes, acrylics or styrene-acrylics.
    According to one implementation of the method, the method further comprises a step of drying or crosslinking the polymer before the step of pouring fresh concrete.
    This step may for example be carried out when the structural adhesive material is a polymer of the styrene-acrylic family.
    According to one implementation of the method, the concrete has a water-cement ratio (W / C) of at most 1, preferably from 0.20 to 0.27.
    According to one implementation of the method, the concrete is a high performance concrete, an ultra high performance concrete, a self-placing concrete or a foamed concrete.
    This type of concrete adheres particularly well to the structural adhesive material.
    According to one implementation of the method, the method further comprises a subsequent demolding step, preferably 18 hours after the casting step of the fresh concrete.
    According to one implementation of the method, the method further comprises a subsequent heat treatment step after the demolding step.
    This arrangement improves the cohesion between the different materials used to make the prefabricated element.
    The present invention also relates to a prefabricated element that can be obtained by a method as described above in which at least a portion of the connectors of the at least one photovoltaic module are made in concrete.
    In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended diagrammatic drawing showing, by way of nonlimiting example, the various steps of a method of manufacturing a prefabricated element. according to the invention.
    Figure 1 illustrates the arrangement between the formwork mold and the photovoltaic module according to a first implementation of the method according to the invention.
    FIG. 2 is a profile view of a prefabricated element obtained from the first implementation of the method according to the invention illustrated in FIG.
    Figure 3 illustrates the arrangement between the formwork mold and the photovoltaic module according to a second implementation of the method according to the invention.
    FIG. 4 is a profile view of a prefabricated element obtained from the second implementation of the method according to the invention illustrated in FIG. 3.
    As illustrated in FIGS. 1 and 3, the implementation of a method of manufacturing a prefabricated element 1 intended for the construction and production of electricity according to the invention consists first of all in having at least a photovoltaic module 2 intended to produce electricity.
    In the example of Figures 1 and 2, the prefabricated element 1 comprises a single photovoltaic module 2 while in the example shown in Figures 3 and 4 the prefabricated element comprises two photovoltaic modules 2.
    Of course, the present invention could comprise a different number of photovoltaic modules 2, this number being determined according to the applications envisaged for the prefabricated element 1.
    A photovoltaic module 2 generally comprises a plurality of photovoltaic cells electrically connected together in series.
    Photovoltaic cells can be based on inorganic compounds, metal compounds, organic compounds or organic-mineral hybrid compounds also called hybrid photovoltaic cells.
    The mineral or metallic compounds suitable for producing the photovoltaic cells may be based on amorphous silicon, crystalline silicon, polycrystalline silicon, liquid silicon, cadmium telluride, copper-indium-selenium, copper-indium-gallium- selenium, copper-indium-gallium-diselenide-disulphide, gallium arsenide, copper-zinc-tin-selenium, copper-zinc-tin-diselenide-disulphide, indium-tin oxide, copper , molybdenum, chalcopyrite or mixtures thereof.
    The organic compounds suitable for producing the photovoltaic cells may be based on two compounds, one electron donor and the other electron acceptor. Among the electron donors, mention may be made of polyarylenes, poly (arylene-vinylene) s, poly (arylene-ethynylene) s or mixtures thereof. By way of example, mention may be made of poly-3-hexylthiophene (also known as P3HT)) or poly [2-methoxy-5- (3,7-dimethyloctyloxy) -1,4-phenylenevinylene] (also called MDMO-PPV).
    Among the electron acceptors there may be mentioned compounds based on fullerene such as methyl [6,6] -phenyl-C61-butanoate (also known as PCBM).
    It can also be envisaged that the photovoltaic cells can be composed of photosensitive pigments; this is called a dye cell or a Graëtzel cell (also known as DSSC or DSC). Among the photosensitive pigments constituting photovoltaic cells with dyes or Graëtzel, mention may be made of titanium dioxide. All photovoltaic cells forming a photovoltaic module 2 are covered with a transparent polymer resistant to external aggressions (water, air, UV ...).
    This polymer will serve as a preferred support for a structural adhesive material described later in the text.
    The photovoltaic module 2 has the shape of a rectangular panel with a front face 2a and a rear face 2b.
    The front face 2a is intended to be oriented towards a light source so as to allow the photovoltaic cells to generate the photovoltaic effect.
    The rear face 2b is opposite to the front face 2a.
    In addition, the photovoltaic module 2 comprises two electrical connectors C1, C2 protruding from the rear face 2b.
    These electrical connectors C1, C2 are used to recover the electricity produced by the photovoltaic module 2.
    The second step of the manufacturing method according to the invention consists in having a formwork mold 4.
    In the example shown, the form mold 4 has the general shape of a parallelepiped comprising several walls, including four side walls 4a, 4b, 4c, 4d positioned vertically and a bottom wall 4e positioned horizontally.
    These walls 4a, 4b, 4c, 4d, 4e define two zones of the space, a first zone of the space located inside the formwork mold 4, called inner zone I of the formwork mold 4, and a second zone of the space located outside the formwork mold 4, called outer zone E to the formwork mold 4.
    In addition, the formwork mold also comprises an opening 5 arranged facing the bottom 4e, and used in a subsequent step for the introduction of fresh concrete 6 into the mold of the formwork 4.
    The formwork mold 4 used can be made from several materials, such as bakelized wood, polyvinyl chloride (PVC), polydimethylsiloxane (PDMS) or steel.
    After this step, several variants are possible to introduce the photovoltaic mold 2 in the formwork mold 4.
    A first of these variants consists in positioning the at least one photovoltaic module 2 against one of the walls 4a, 4b, 4c, 4d, 4e of the formwork mold 4, the front face 2a of the photovoltaic module 2 being disposed opposite said wall 4a, 4b, 4c, 4d, 4e.
    Preferably, the photovoltaic module 2 is dimensioned so that its front face 2a completely covers the inner face of the wall 4a, 4b, 4c, 4d, 4e against which it is positioned.
    In the example illustrated in Figures 1 and 2, the photovoltaic module 2 has been positioned against the bottom wall 2e.
    A second of these variants consists in replacing one of the walls 4a, 4b, 4c, 4d, 4e of the formwork mold by all or part of the at least one photovoltaic module 2, the front face 2a of the photovoltaic module 2 being arranged opposite an area outside the formwork mold 4.
    In the example illustrated in Figures 3 and 4, the prefabricated element 1 comprises two photovoltaic modules 2, both vertically arranged and replacing two side walls 4a, 4b, 4c, 4d opposite.
    Thus, the two photovoltaic modules 2 are used as lost coffers.
    In this variant, end portions of the rear face 2b can be positioned facing the sidewall of other adjacent walls of the formwork mold 4. Applying a seal between these end portions of the rear face 2b of the photovoltaic module 2 and a wall 4a, 4b, 4c, 4d, 4e of the formwork mold 4 or end portions of the rear face 2b of another photovoltaic module 2, potentially reinforced by a metal frame disposed around the formwork mold 4 and acting as a clamp, may be used to ensure cohesion between the different walls 4a, 4b, 4c, 4d, 4e of the formwork mold 4.
    A combination of these two variants can also be envisaged, for example by positioning the front face of a photovoltaic module 2 against a wall 4a, 4b, 4c, 4d, 4e of the formwork mold 4, and replacing another of these walls. 4a, 4b, 4c, 4d, 4e by a photovoltaic module 2 whose front face would be oriented opposite the outer zone E to the formwork mold 4.
    The method according to the invention also comprises a step of depositing a structural adhesive material 3 on all or part of the rear face 2b of the at least one photovoltaic module 2 disposed facing the inner zone I of the formwork mold 4.
    This structural adhesive material 3 can be applied to the rear face 2b of the photovoltaic module 2 by spraying, using a roller or with the aid of a brush.
    This step can be performed before or after the introduction of the photovoltaic panel 2 into the formwork mold 4.
    The structural adhesive material 3 is preferably a polymer, for example an epoxy adhesive or an acrylic adhesive.
    According to a variant of the invention, the method may comprise a preliminary step of sanding the rear face 2b of the photovoltaic module 2.
    This sanding step makes it possible to increase the specific surface area of the rear face 2b of the photovoltaic module 2, which promotes the adhesion of the polymer.
    This step may optionally be followed by cleaning with a cloth soaked in solvent to remove the dust and facilitate the application of the polymer.
    The method then comprises a step of pouring a fresh concrete 6 into the form mold 4 so as to cover the structural adhesive material 3.
    The fresh concrete 6 is introduced into the form mold 4 through the opening 5 until the final shape of the prefabricated element 1 is reached.
    Fresh concrete is preferably high performance concrete or ultra high performance concrete.
    However, tests have shown that other concrete formulations also make it possible to manufacture a prefabricated element 1 comprising a photovoltaic module 2, especially a self-placing concrete or foamed concrete.
    In the case of using a structural adhesive material 3 of the epoxy glue type, then the concrete is introduced even though the epoxy glue is still fluid, typically after 15 minutes after the application of the glue.
    The bonding is done at room temperature and the heat input produced by the hydration reaction of the concrete accelerates the bonding.
    In the case of a use of structural adhesive material 3 of the acrylic glue type, then the concrete is introduced once the glue is dry and crosslinked, typically after 15 to 30 minutes depending on the ambient temperature, knowing that the higher the ambient temperature, the lower the crosslinking time.
    Once the glue is crosslinked, the fresh concrete 6 can be poured into the formwork mold 4 up to a period of up to 48 hours.
    The method according to the invention could possibly be used for manufacturing in so-called thin prefabricated elements, for example those having a ratio between the length and the thickness greater than about 10, generally having a thickness of 10 to 30 mm, for example facade cladding elements.
    Such facade cladding elements are preferably manufactured according to the implementation of the method illustrated in FIGS. 1 and 2 in which the photovoltaic module 2 is placed horizontally against the bottom wall 2e of the shuttering mold 4.
    Prefabricated elements 1 more structural are preferably manufactured according to the implementation of the method illustrated in Figures 3 and 4 wherein the photovoltaic module 2 is placed vertically against a side wall 2a, 2b, 2c, 2d of the formwork mold 4.
    Although the invention has been described in connection with particular embodiments, it is obvious that it is not limited thereto and that it includes all the technical equivalents of the means described and their combinations.
    Examples, illustrating the invention without limiting the scope of protection, will be described below.
