Abstract:
Recently, Cu2ZnSnS4 (CZTS) has emerged as one of the most promising thin film materials due to its being environment friendly, abundant in storage and low cost. To date, solar cell with up to 12.6%e?ciency have been reached with using Cu2ZnSn(S, Se)4 (CZTSSe) absorber by hydrazine solution method. In this paper, the structural, optical, electrical, interface layer properties of CZTS thin films are introduced and the effect of sodium diffusion on the CZTS thin film is also discussed. Furthermore, different methods to fabricate CZTS thin films and the corresponding device performances are discussed. Finally, the existing problems and future researches are summarized.
