Abstract
Results of the study of structural and optical properties of Cu2ZnSn(S,Se)4 thin films obtained by sulfitation (selenization) of Cu2ZnSn films which were sputtered by target direct current magnetron sputtering using a stoichiometric Cu2ZnSn (99.99%) target are presented. It has been found that Cu2ZnSn(S,Se)4 thin films are polycrystalline with a grain size of ~60 nm. The optical bandgap of Cu2ZnSnS4 (Eg op = 1.65 eV) and Cu2ZnSnSe4 (Rg op = 1.2 eV) thin films have been determined.
