Abstract

L'invention concerne une cellule solaire. La cellule comporte une série de cellules élémentaires 400 formées dans un substrat semiconducteur commun et séparées les unes des autres par des rainures comportant une partie large 407 formée à partir de la surface inférieure de la cellule et une partie très étroite 410 formée à partir de la surface supérieure de la cellule de sorte que l'espace mort 402 est très petit En outre, les cellules élémentaires ont une largeur telle que le rayonnement frappant la surface supérieure de la cellule est toujours incident à un point qui est situé à une distance inférieure à une distance optimale prédéterminée de l'une au moins des parois latérales de la cellule élémentaire. L'invention permet de réaliser une cellule à rendement élevé sans utiliser de lentilles de focalisation.The invention relates to a solar cell. The cell comprises a series of elementary cells 400 formed in a common semiconductor substrate and separated from each other by grooves comprising a wide part 407 formed from the lower surface of the cell and a very narrow part 410 formed from the cell. upper surface of the cell so that the dead space 402 is very small In addition, the elementary cells have a width such that the radiation hitting the upper surface of the cell is always incident at a point which is located at a distance less than a predetermined optimum distance from at least one of the side walls of the elementary cell. The invention enables a high efficiency cell to be produced without the use of focusing lenses.
