Title: SOLAR CELL WITH A SILICON HETEROJUNCTION
Abstract:
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.
