ABSTRACT:
A process for producing an integrated solar cell comprising deposited unit cells having a p-i-n junction, with an n-type layer forming an n-p Junction between unit cells comprising a microcrystalline amorphous silicon layer, in which said microcrystalline amorphous silicon layer is subjected to a hydrogen discharge treatment for a given period of time. By the hydrogen discharge treatment, the film resistance of the n-type layer is reduced to accelerate ohmic property with a p-type layer thereby achieving increased conversion efficiency.
