Description

Dispositif photovoltaïque non plan  Non-planar photovoltaic device
L'invention concerne un procédé de fabrication d'un dispositif photovoltaïque ainsi qu'un dispositif photovoltaïque en tant que tel. The invention relates to a method of manufacturing a photovoltaic device and a photovoltaic device as such.
La figure 1 illustre un module photovoltaïque 1 selon l'état de la technique. Il se présente sous la forme d'une grande dalle carrée mesurant entre 1 et 3 mètres de côté, comprenant plusieurs cellules photovoltaïques 2 liées entre elles, et dont les conducteurs électriques 3 de surface sont reliés entre eux, par exemple par soudure, pour finalement conduire le courant généré par l'ensemble des cellules photovoltaïques 2 vers une boîte de jonction 5 disposée sous le module, qui sert à le relier électriquement avec d'autres modules. Les cellules photovoltaïques 2 sont de plus recouvertes d'une vitre en verre 6 protectrice, au niveau de la surface supérieure du module. Enfin, la face inférieure des cellules photovoltaïques 2 est protégée par un polymère laminé 4. FIG. 1 illustrates a photovoltaic module 1 according to the state of the art. 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. The photovoltaic cells 2 are further covered with a protective glass pane 6 at the upper surface of the module. Finally, the underside of the photovoltaic cells 2 is protected by a laminated polymer 4.
L'utilisation de modules photovoltaïques 1 tels que décrits ci-dessus est très répandue et leur format est quasi standardisé. Toutefois, il existe des implémentations particulières, comme le positionnement en toiture d'un bâtiment afin de produire de l'électricité pour répondre à une partie des besoins du bâtiment, pour lesquelles les dimensions et/ou forme décrites ci-dessus ne sont pas optimales. Pour améliorer l'intégration des dispositifs photovoltaïques en toiture, il est connu de fabriquer des dispositifs photovoltaïques comprenant la même structure que celle décrite en référence avec la figure 1 mais de format réduit, se présentant dans une forme de tuiles plates, pour pouvoir les disposer sur une toiture en remplacement des tuiles existantes avec la même technique de construction. Ces solutions existantes restent toutefois insatisfaisantes car complexes et coûteuses à fabriquer. De plus, elles ne permettent pas de répondre à toutes les exigences esthétiques architecturales, notamment pas de remplacer les tuiles de forme courbée, comme les tuiles romanes très répandues. De manière plus générale, les dispositifs photovoltaïques standards ne permettent pas une implémentation sur des surfaces courbes, ce qui limite le développement de leur utilisation. The use of photovoltaic modules 1 as described above is widespread and their format is almost standardized. However, there are specific implementations, such as the positioning on the roof of a building to produce electricity to meet a part of the building needs, for which the dimensions and / or form described above are not optimal. . To improve the integration of photovoltaic devices on the roof, it is known to manufacture photovoltaic devices comprising the same structure as that described with reference to Figure 1 but of reduced size, being in a form of flat tiles, to be able to arrange them on a roof to replace existing tiles with the same construction technique. These existing solutions however remain unsatisfactory because complex and expensive to manufacture. 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.
Ainsi, il existe un besoin d'une solution permettant de pallier aux inconvénients mentionnés ci-dessus et un objet de l'invention est notamment de proposer un dispositif photovoltaïque adapté pour une surface courbe. Thus, there is a need for a solution to overcome the drawbacks mentioned above and an object of the invention is in particular to provide a photovoltaic device adapted for a curved surface.
A cet effet, l'invention repose sur un procédé de fabrication d'un dispositif photovoltaïque, caractérisé en ce qu'il comprend les étapes suivantes : For this purpose, the invention is based on a method of manufacturing a photovoltaic device, characterized in that it comprises the following steps:
- assemblage d'au moins une cellule photovoltaïque avec un substrat souple ; puis,  - Assembling at least one photovoltaic cell with a flexible substrate; then,
- réalisation de découpes dans la au moins une cellule photovoltaïque pour lui apporter une souplesse et permettre de déformer le dispositif photovoltaïque. Le procédé de fabrication d'un dispositif photovoltaïque peut comprendre les étapes préalables suivantes :  - Making cuts in the at least one photovoltaic cell to provide flexibility and allow to deform the photovoltaic device. The method of manufacturing a photovoltaic device may include the following preliminary steps:
- réalisation de rainures dans le substrat souple ;  - Making grooves in the flexible substrate;
- formation de conducteurs électriques dans ces rainures. La réalisation des conducteurs électriques dans les rainures peut être faite par dépôt de métal dans un bain électrochimique.  - Formation of electrical conductors in these grooves. The realization of the electrical conductors in the grooves can be made by depositing metal in an electrochemical bath.
La réalisation de découpes dans la au moins une cellule photovoltaïque peut être réalisée par gravure laser. L'assemblage d'au moins une cellule photovoltaïque avec un substrat souple peut être obtenu par polymérisation, ou réticulation, ou soudure, ou collage. Le procédé de fabrication d'un dispositif photovoltaïque peut comprendre une étape supplémentaire consistant à conformer le dispositif photovoltaïque dans une forme non plane. 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.
Le procédé de fabrication d'un dispositif photovoltaïque peut comprendre une étape supplémentaire consistant à ajouter une couche transparente de protection de type résine sur le dispositif photovoltaïque. 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.
L'invention porte aussi sur un dispositif photovoltaïque, caractérisé en ce qu'il comprend au moins une cellule photovoltaïque présentant des découpes, assemblée à un substrat souple, pour former un ensemble souple et/ou de forme non plane. 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.
Le substrat souple peut comprendre des rainures comprenant des conducteurs qui n'occupent pas toute la hauteur des rainures, et les rainures peuvent comprendre aussi des conducteurs de cellules photovoltaïques en contact avec les conducteurs du substrat souple. 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.
Le substrat souple peut comprendre une couche inférieure sous forme de film et une couche de résine de type polymère, et les rainures peuvent s'étendre sur tout ou partie de l'épaisseur de la couche de résine. 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.
Les rainures peuvent être disposées de manière superposée aux conducteurs en relief à la surface de la au moins une cellule photovoltaïque de sorte que ces conducteurs sont tous logés dans des rainures du substrat souple. Les découpes peuvent occuper tout ou partie de l'épaisseur d'une cellule photovoltaïque, et/ou l'épaisseur d'une cellule photovoltaïque plus du substrat souple peut être inférieure ou égale à 250 μητι, ou inférieure ou égale à 200 μητι, et/ou le dispositif photovoltaïque peut présenter une forme non plane présentant au moins une courbure de rayon de courbure inférieur ou égal à 1 mètre. 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 μητι, or less than or equal to 200 μητι, 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.
Le dispositif de couverture d'un toit peut comprendre un assemblage de dispositifs photovoltaïques tels que décrits précédemment en forme de tuiles de surface arrondie et/ou courbée et/ou galbée. 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.
L'invention porte aussi sur un tissu caractérisé en ce qu'il comprend des dispositifs photovoltaïques tels que décrits précédemment. The invention also relates to a fabric characterized in that it comprises photovoltaic devices as described above.
L'invention porte aussi sur un véhicule automobile, caractérisé en ce qu'il comprend des dispositifs photovoltaïques tels que décrits précédemment sur sa surface. Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante d'un mode de réalisation particulier fait à titre non-limitatif en relation avec les figures jointes parmi lesquelles : La figure 1 représente en perspective éclatée la structure d'un module photovoltaïque selon l'état de la technique. The invention also relates to a motor vehicle, characterized in that it comprises photovoltaic devices as previously described on its surface. These objects, features and advantages of the present invention will be described in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the attached figures among which: FIG. 1 represents in exploded perspective the structure of FIG. a photovoltaic module according to the state of the art.
La figure 2 représente schématiquement une première étape du procédé de fabrication d'un dispositif photovoltaïque selon un mode de réalisation de l'invention. La figure 3 représente schématiquement une seconde étape du procédé de fabrication d'un dispositif photovoltaïque selon le mode de réalisation de l'invention. 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.
La figure 4 représente schématiquement une troisième étape du procédé de fabrication d'un dispositif photovoltaïque selon le mode de réalisation de l'invention. La figure 5 représente un grossissement d'une partie du dispositif photovoltaïque à la fin de la troisième étape selon le mode de réalisation de l'invention. Figure 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.
La figure 6 représente schématiquement un dispositif photovoltaïque selon un mode de réalisation de l'invention. FIG. 6 schematically represents a photovoltaic device according to one embodiment of the invention.
La figure 2 représente ainsi une première étape du procédé de fabrication d'un dispositif photovoltaïque selon un mode de réalisation de l'invention. Ce procédé comprend d'abord la fabrication d'une cellule photovoltaïque 12 ou d'un ensemble de cellules photovoltaïques 12, à base de silicium, selon un procédé de l'état de la technique. Des conducteurs 13 sont disposés sur une surface de cette (ou ces) cellule(s) afin de conduire le courant généré par effet photovoltaïque. Ils ressortent donc en relief sur la surface plane de cette (ou ces) cellule(s). 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).
Selon un élément essentiel de l'invention, le procédé comprend une étape de fabrication d'un substrat souple 20, destiné à recevoir une ou plusieurs cellules photovoltaïques 12. Dans ce mode de réalisation, ce substrat souple 20 comprend une structure multicouches de type polymères : dans le mode de réalisation illustré, il comprend un film 21 dans sa partie inférieure et une couche en résine 22 dans sa partie supérieure. Cette couche en résine 22 comprend des rainures 24 dans son épaisseur, dans lesquelles des conducteurs métalliques 23 sont disposés, par exemple par report d'un ruban métallique ou par dépôt par jet d'encre d'une encre métallique, ou par bain électrochimique à l'aide de masques pour disposer la métallisation spécifiquement dans les rainures, ou par toute autre solution de dépôt de métal. Dans ce mode de réalisation, les rainures 24 s'étendent sur toute l'épaisseur de la couche en résine 22, donc depuis la surface supérieure du film 21 . Les conducteurs 23 n'occupent qu'une partie de la hauteur des rainures 24, laissant libre leur partie supérieure destinée à recevoir les conducteurs 13 des cellules photovoltaïques. Pour cela, la géométrie des rainures 24 correspond à celle des conducteurs 13 des cellules photovoltaïques 12. Pour faciliter cette correspondance, les conducteurs 13 des cellules photovoltaïques sont rectilignes et parallèles, disposés selon un pas p constant. Ils peuvent aussi être sous forme sphérique plus simple à réaliser (coalescence naturelle des alliages et permettant un autocentrage de la cellule sur le substrat, ce qui permet une grande précision de positionnement). La figure 3 illustre le résultat de l'assemblage d'une cellule photovoltaïque 12 avec le substrat souple 20. Il apparaît ainsi que les conducteurs 13 de la cellule photovoltaïque 12 viennent en contact avec les conducteurs 23 des rainures 24, pour former un seul conducteur occupant toute la hauteur des rainures. Le substrat souple 20 et la au moins une cellule photovoltaïque 12 sont ensuite fixés par tout moyen, comme par une polymérisation permettant leur collage, ou par réticulation, etc., pour obtenir la soudure ou collage des deux éléments. According to an essential element of the invention, the method comprises a step of manufacturing a flexible substrate 20 intended to receive one or more photovoltaic cells 12. In this embodiment, 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. In this embodiment, 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. For this, the geometry of the grooves 24 corresponds to that of the conductors 13 of the photovoltaic cells 12. To facilitate this correspondence, 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. It thus appears that 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.
Ensuite, le procédé de fabrication comprend une étape de réalisation de découpes 17 s'étendant sur tout ou partie de l'épaisseur des cellules photovoltaïques 12, comme illustré par les figures 4 et 5, pour former un réseau de découpes 17 prévues pour permettre le pliage ultérieur du dispositif photovoltaïque pour le conformer à une forme tridimensionnelle souhaitée. Pour cela, le réseau de découpes 17 est calculé au préalable par des techniques de type de celles utilisées en origami, afin d'obtenir la forme tridimensionnelle quelconque souhaitée. De même, la profondeur des découpes 17 dans les cellules photovoltaïques 12 dépend du rayon de courbure imposé par la forme courbée finale. Les découpes sont réalisées par tout procédé, comme par des gravures laser. En variante, tout ou partie des découpes peut même s'étendre sur une partie de l'épaisseur du substrat souple. Next, 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. For this, the network of cuts 17 is calculated in advance by techniques of the type used in origami, to obtain any desired three-dimensional shape. Similarly, 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.
En remarque, le substrat souple 20 assure un bon maintien de l'ensemble du dispositif après réalisation des découpes 17, même si ces dernières sont de profondeur importante, tout en limitant le risque de propagation de fissures. De plus, le substrat souple 20 remplit une seconde fonction de continuité électrique pour conduire le courant généré par les différentes parties de cellules photovoltaïques, même après les découpes, puisqu'il est apte à conduire l'électricité entre les zones découpées et vers les autres cellules. Note, 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. In addition, 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.
Le résultat obtenu par les étapes décrites ci-dessus est un dispositif photovoltaïque doté d'une certaine souplesse, plus ou moins importante selon le choix du réseau de découpes 17, qui peut permettre d'obtenir des dispositifs photovoltaïques sous forme de tissus souples, comprenant par exemple une multitude de cellules photovoltaïques fixées de manière adjacente sur un même substrat souple. Cette approche permet ensuite à un utilisateur final d'utiliser le tissu pour toute utilisation nécessitant une souplesse du matériau, comme dans le textile, pour une implémentation sur un vêtement par exemple. Le procédé de fabrication peut comprendre une étape finale qui consiste à déformer, conformer le résultat de forme plane tel que représenté sur la figure 4, pour atteindre un produit final de forme tridimensionnelle comme une tuile de forme galbée, dont la forme est ensuite figée en ajoutant par exemple une résine transparente 30 de protection sur tout ou partie de sa surface, pour obtenir le produit final tel que représenté à titre d'exemple par la figure 6. Naturellement, ce principe peut aussi être utilisé plus généralement pour recouvrir toute surface non plane de dispositifs photovoltaïques, comme un véhicule automobile par exemple. La solution est adaptée pour des rayons de courbure importants, inférieur ou égal à 1 mètre par exemple. 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. 4 to reach a final product of three-dimensional shape such as a curved shaped tile, the shape of which is then fixed in adding for example a transparent protective resin 30 on all or part of its surface, to obtain the final product as represented by way of example in FIG. 6. Naturally, 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.
En remarque, le mode de réalisation a été implémenté avec des cellules photovoltaïques comprenant des conducteurs sur leur face arrière. En variante, le même procédé pourrait être utilisé avec des cellules comprenant des conducteurs sur leur face avant ou sur leurs deux faces. D'autre part, la solution proposée permet de former une structure finale (telle que représentée sur la figure 4) peu épaisse, dont l'épaisseur est inférieure à 250 μιτι, voire inférieure ou égale à 200 μιτι. La ou les cellule(s) photovoltaïque(s) présente(nt) une épaisseur comprise entre 50 et 250 μιτι. Le substrat souple 20 présente avantageusement une épaisseur comprise entre 100 et 1000 μιτι. As a remark, the embodiment has been implemented with photovoltaic cells comprising conductors on their rear face. In a variant, the same method could be used with cells comprising conductors on their front face or on their two faces. On the other hand, 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 μιτι, or even less than or equal to 200 μιτι. The cell (s) photovoltaic (s) has (s) a thickness of between 50 and 250 μιτι. The flexible substrate 20 advantageously has a thickness between 100 and 1000 μιτι.
