Low cost thin film solar cells have great development space and application prospects in the photovoltaic field. Copper-zinc-tin-sulfur-selenium (Cu2ZnSn(S, Se)4, CZTSSe) thin film solar cells have many advantages, such as high abundance, non-toxic, high light absorption coefficient， a suitable optical band gap, high theory optoelectronic conversion efficiency and stable characteristic. So it is a kind of novel thin film photovoltaic cells with great scale application potential. The development history, preparation methods and research status of CZTSSe thin film solar cells are introduced in this paper. By comparative analyzing the reported CZTSSe thin film solar cells, the current achievements and status of CZTSSe thin film solar cells are summarized. Finally, the current problems about CZTSSe thin film solar cells are demonstrated and their future perspectives are presented.
