摘要

The highest efficient CuZnSn(S,Se) (CZTSSe) Solar cell have a Cu-poor and Zn-rich metal ratio compared to the stoichiometry. Therefore secondary phases, such as Zn(S,Se), are formed. To investigate a possible correlation between these secondary phases and the solar cell properties, four samples were prepared which have efficiencies of 4.85–6.27%. In the semiconducting CZTSSe films, different amounts of Zn(S,Se) and SnSe are observed, and a correlation with solar cell properties is found. From the experimental results, conclusions about the influence of secondary phases on the cell efficiency are obtained.
