Abstract
The invention concerns a silicon heterojunction solar cell successively comprising:
- a substrate of doped crystalline silicon,a passivation layer,a layer of doped amorphous silicon of opposite type to the substrate,a layer of transparent conducting material,said cell being characterized in that, between the substrate and the passivation layer, it comprises a layer of crystalline material having so-called “high minority carrier mobility” in which the mobility of the substrate minority carriers is greater than the mobility of said minority carriers in the substrate.
