This paper examines CuIn(Se,S)2 (CISS) films prepared by sputtering precursor films of In, Cu, and In2S3 onto Mo coated soda-lime glass, followed by a single-stage selenium annealing process to form a CISS chalcopyrite phase. In this study, S was substituted for Ga to increase the energy gap of CuInSe-based materials. Experimental results reveal that the composition of (S + Se) and S decreased slightly with an increase in the selenium annealing temperature, exhibiting uniform distribution throughout the entire CISS film sample. The resulting CISS film exhibited p-type conductivity with an energy gap of 1.11eV. The optimum selenium annealing condition for the CIGS precursor prepared by sputtering was 798 K for 20 minutes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
