Abstract : To alleviate the limitations of pure sulfide Cu 2 ZnSnS 4 (CZTS) thin film, such as band gaps adjustment, antisite defects, secondary phase and microstructure, Cadmium is introduced into CZTS thin film to replace Zn partially to form Cu 2 Zn 1− x Cd x SnS 4 (CZCTS) thin film by low-cost sol–gel method. It is demonstrated that the band gaps and crystal structure of CZCTS thin films are affected by the change in Zn/Cd ratio.
