Abstract:
A compound solar cell having a higher conversion efficiency and a method for producing the compound solar cell at lower costs are provided. The compound solar cell includes a CIGS light absorbing layer, a buffer layer and a front side electrode layer provided on a substrate. An interface layer made of a mixed crystal compound having a composition represented by the following general formula is provided between the CIGS light absorbing layer and the buffer layer: Zn(Ox,S1-x) . . . (1), wherein X is 0.9
