It is in the form of a large square slab measuring between 1 and 3 meters apart, comprising several photovoltaic cells 2 interconnected, and whose surface electrical conductors 3 are interconnected, for example by welding, to finally conduct the current generated by all the photovoltaic cells 2 to a junction box 5 disposed under the module, which serves to connect it electrically with other modules.

Moreover, they do not allow meet all architectural aesthetic requirements, including not replacing curved tiles, such as Roman tiles. More generally, standard photovoltaic devices do not allow an implementation on curved surfaces, which limits the development of their use.

- the method of manufacturing a photovoltaic device may include the following preliminary steps:
- the realization of the electrical conductors in the grooves can be made by depositing metal in an electrochemical bath.
- the making of cuts in the at least one photovoltaic cell can be performed by laser etching.
- the assembly of at least one photovoltaic cell with a flexible substrate can be obtained by polymerization, or crosslinking, or welding, or bonding.
- the method of manufacturing a photovoltaic device may comprise a further step of shaping the photovoltaic device into a non-planar shape.
- the method of manufacturing a photovoltaic device may comprise an additional step of adding a transparent protective layer of resin type to the photovoltaic device.
- the invention also relates to a photovoltaic device, characterized in that it comprises at least one photovoltaic cell having cutouts, assembled to a flexible substrate, to form a flexible assembly and / or non-planar shape.
- the flexible substrate may comprise grooves comprising conductors that do not occupy the full height of the grooves, and the grooves may also include photovoltaic cell conductors in contact with the conductors of the flexible substrate.
- the flexible substrate may comprise a lower layer in the form of a film and a layer of polymer-type resin, and the grooves may extend over all or part of the thickness of the resin layer.
- the grooves may be arranged superimposed on the raised conductors on the surface of the at least one photovoltaic cell so that these conductors are all housed in grooves of the flexible substrate.
- the blanks may occupy all or part of the thickness of a photovoltaic cell, and / or the thickness of a photovoltaic cell plus the flexible substrate may be less than or equal to 250 ⁇ , or less than or equal to 200 ⁇ , and or the photovoltaic device may have a non-planar shape having at least one curvature of radius of curvature less than or equal to 1 meter.
- the covering device of a roof may comprise an assembly of photovoltaic devices as previously described in the form of rounded surface tiles and / or curved and / or curved.
- the invention also relates to a fabric characterized in that it comprises photovoltaic devices as described above.
- FIG. 1 represents in exploded perspective the structure of FIG. a photovoltaic module according to the state of the art.
- Figure 2 schematically shows a first step of the method of manufacturing a photovoltaic device according to one embodiment of the invention.
- Figure 3 schematically shows a second step of the method of manufacturing a photovoltaic device according to the embodiment of the invention.
- FIG. 4 schematically shows a third step of the method of manufacturing a photovoltaic device according to the embodiment of the invention.
- FIG. 5 represents a magnification of a portion of the photovoltaic device at the end of the third step according to the embodiment of the invention.
- FIG. 6 schematically represents a photovoltaic device according to one embodiment of the invention.
- FIG. 2 thus represents a first step in the method of manufacturing a photovoltaic device according to one embodiment of the invention.
- This method first comprises the manufacture of a photovoltaic cell 12 or a set of photovoltaic cells 12, based on silicon, according to a method of the state of the art.
- Conductors 13 are arranged on a surface of this (or these) cell (s) in order to conduct the current generated by photovoltaic effect. They stand out in relief on the flat surface of this (or these) cell (s).
- the method comprises a step of manufacturing a flexible substrate 20 intended to receive one or more photovoltaic cells 12.
- this flexible substrate 20 comprises a polymer-type multilayer structure : in the illustrated embodiment, it comprises a film 21 in its part lower and a resin layer 22 in its upper part.
- This resin layer 22 comprises grooves 24 in its thickness, in which metal conductors 23 are arranged, for example by transfer of a metal ribbon or by ink jet deposition of a metallic ink, or by electrochemical bath to using masks to arrange the metallization specifically in the grooves, or by any other metal deposition solution.
- the grooves 24 extend over the entire thickness of the resin layer 22, hence from the upper surface of the film 21.
- the conductors 23 occupy only part of the height of the grooves 24, leaving their upper part for receiving the conductors 13 of the photovoltaic cells.
- the geometry of the grooves 24 corresponds to that of the conductors 13 of the photovoltaic cells 12.
- the conductors 13 of the photovoltaic cells are rectilinear and parallel, arranged in a constant pitch p. They can also be in spherical form simpler to achieve (natural coalescence alloys and allowing self-centering of the cell on the substrate, which allows a high positioning accuracy).
- FIG. 3 illustrates the result of the assembly of a photovoltaic cell 12 with the flexible substrate 20.
- the conductors 13 of the photovoltaic cell 12 come into contact with the conductors 23 of the grooves 24, to form a single conductor occupying the entire height of the grooves.
- the flexible substrate 20 and the at least one photovoltaic cell 12 are then fixed by any means, such as by a polymerization allowing their bonding, or by crosslinking, etc., to obtain the welding or bonding of the two elements.
- the manufacturing method comprises a step of making cutouts 17 extending over all or part of the thickness of the cells.
- photovoltaic 12 as illustrated by Figures 4 and 5, to form a network of cutouts 17 provided to allow the subsequent folding of the photovoltaic device to conform to a desired three-dimensional shape.
- the network of cuts 17 is calculated in advance by techniques of the type used in origami, to obtain any desired three-dimensional shape.
- the depth of the cuts 17 in the photovoltaic cells 12 depends on the radius of curvature imposed by the final curved shape.
- the cuts are made by any method, such as laser engraving. Alternatively, all or part of the cuts may even extend over a portion of the thickness of the flexible substrate.
- the flexible substrate 20 ensures a good maintenance of the entire device after making the cuts 17, even if the latter are of significant depth, while limiting the risk of crack propagation.
- the flexible substrate 20 fills a second function of electrical continuity to conduct the current generated by the different parts of photovoltaic cells, even after the cuts, since it is able to conduct electricity between the cut areas and to the others cells.
- the result obtained by the steps described above is a photovoltaic device provided with a certain flexibility, more or less important depending on the choice of the network of cuts 17, which can make it possible to obtain photovoltaic devices in the form of flexible fabrics, comprising for example a multitude of photovoltaic cells attached adjacent to the same flexible substrate.
- This approach then allows an end user to use the fabric for any use requiring flexibility of the material, as in the textile, for implementation on a garment for example.
- the manufacturing process may comprise a final step consisting in deforming and shaping the result of planar shape as shown in FIG.
- this principle can also be used more generally to cover any non-surface plane of photovoltaic devices, such as a motor vehicle for example.
- the solution is suitable for large radii of curvature, less than or equal to 1 meter for example.
- the embodiment has been implemented with photovoltaic cells comprising conductors on their rear face.
- the same method could be used with cells comprising conductors on their front face or on their two faces.
- the proposed solution makes it possible to form a thin final structure (as shown in FIG. 4), the thickness of which is less than 250 ⁇ , or even less than or equal to 200 ⁇ .
- the cell (s) photovoltaic (s) has (s) a thickness of between 50 and 250 ⁇ .
- the flexible substrate 20 advantageously has a thickness between 100 and 1000 ⁇ .
