ABSTRACT:
A solar cell device includes an absorber layer or heterojunction-forming layer which comprises a I-III-VI.sub.2 chalcopyrite semiconductor film containing a Group VIIA element as a dopant. The semiconductor film can be made by depositing a I-III-VI.sub.2 chalcopyrite compound film onto a substrate while evaporating onto the substrate a Group VIIA element to obtain a I-III-VI.sub.2 chalcopyrite compound film containing a Group VIIA element therein as a dopant.
