In our laboratory, Cu2ZnSn(S,Se)4 (CZTSSe) films are prepared by selenization of spin coated CZTS precursors. In this study, different temperatures are tested for the selenization process and their effects on the device are investigated. The influence of the selenization temperature on the Se incorporation and structural properties of the absorber have

Selenate precursor for synthesis of CZTSSe: Performance as thinfilm solar cell
Journal of Alloys and Compounds, 2019Abstract Copper and Zinc selenates were synthesized by wetchemical method employing selenic acid. The selenates were mixed with SnS2 in the ratio of 1:1:1 and annealed at 350˚and 450 °C to obtain CZTSSe. The synthesized CZTSSe possess absorption coefficient as high as 105 cm−1. The obtained band gap of the samples are 1.62 and 2.69 eV.

Impact of Minor Phases on the Performances of CZTSSe Thin-Film Solar Cells
Chemistry of Materials, 2016Cu2ZnSn(S1–xSex)4 (CZTSSe) alloys are promising candidates for low-cost and high-efficiency thin-film solar cells. Compared to CdTe and Cu(InxGa1–x)Se2, CZTSSe uses chemicals found more abundantly on earth. This key aspect as well as its optical properties—band gap range of 1.0–1.5 eV and absorption coefficient larger than 104 cm–1—makes CZTSSe a ...
