Thin-film solar cells based on Cu 2 ZnSn(S,Se) 4 (CZTSSe) are a promising technology for developing high-efficiency photo voltaic cells. These cells have excellent optical properties, a high absorption coefficient of over 10 4  cm −1 , and are made from abundant, non-toxic materials. The bandgap of...
