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.
