Title (EN) SOLAR CELL WITH A SILICON HETEROJUNCTION
(FR) CELLULE SOLAIRE A HETEROJONCTION DE SILICIUM
Abstract: front page image
(EN)The invention relates to a solar cell with a silicon heterojunction, successively comprising: a doped crystalline silicon substrate (1); a passivation layer (2a); a layer (2b) of doped amorphous silicon of the opposite type to that of the substrate (1); and a layer (3) of a conductive transparent material; said cell being characterised in that it comprises, between the substrate (1) and the passivation layer (2a), a layer (5) of a crystalline material with a so-called "high mobility of minority carriers" wherein the mobility (μm) of the minority carriers of substrate (1) is higher than the mobility of said minority carriers in substrate (1). The invention also relates to a method for producing such a solar cell.
(FR)L'invention concerne une cellule solaire à hétérojonction de silicium, comprenant successivement : - un substrat (1) de silicium cristallin dopé, - une couche (2a) de passivation, - une couche (2b) de silicium amorphe dopé de type opposé à celui du substrat (1), - une couche (3) d'un matériau transparent conducteur, ladite cellule étant caractérisée en ce qu'elle comprend, entre le substrat (1) et la couche (2a) de passivation, une couche (5) d'un matériau cristallin dit « à forte mobilité de porteurs minoritaires » dans lequel la mobilité (μm) des porteurs minoritaires du substrat (1) est supérieure à la mobilité desdits porteurs minoritaires dans le substrat (1). L'invention concerne également un procédé de fabrication d'une telle cellule solaire.
