Abstract:
A method of fabricating a photovoltaic device includes a step of forming an absorber layer above a substrate, and a step of forming a surface layer on the absorber layer. The absorber layer includes an I-III-VI2 compound, which contains a Group I element, a Group III element and a Group VI element. The surface layer includes an I-III-VI2 compound, which contains a Group I element, a Group III element and a Group VI element, and has an atomic ratio of the Group I element to the Group III element in the range of from 0.1 to 0.9.
