Patent

CA 2421257

The present invention pertains to a solar cell unit comprising a back electrode, a photovoltaic (PV) layer, and, optionally, a front electrode, with part of the surface of the solar cell unit not generating energy, wherein at least part of the non-energy-generating part of the solar cell unit is provided with a coloring material, while at least part of the energy- generating part of the solar cell unit is free of a coloring material, the color of the coloring material being different from that of the solar cell unit. If so desired, part of the non-energy-generating part of the solar cell unit may be provided with a camouflage material. The present invention makes it possible to select the color impression of the solar cell unit and/or decorate the solar cell unit while the electrical output of the solar cell unit is not affected.

L'invention concerne une cellule solaire comprenant une électrode noire, une couche photovoltaïque (PV), et éventuellement, une électrode frontale. Une zone de la surface de la cellule solaire ne génère pas d'énergie, au moins une partie de ladite zone présentant une matière colorante, alors qu'au moins une partie de la zone générant de l'énergie de la cellule solaire est exempte de matière colorante, la couleur de cette matière étant différente de celle de la cellule solaire. Il est possible de revêtir la partie de la zone ne générant pas d'énergie de la cellule solaire avec une matière de camouflage. Il est possible, grâce à l'invention, de choisir l'impression couleurs de la cellule solaire et/ou de décorer celle-ci sans porter préjudice à la sortie électrique de la cellule.
