Detection of ZnS phases in CZTS thin-films by EXAFS
Hartman, Katy; Newman, Bonna K.; Johnson, J. L.; Du, Hui; Fernandes, P. A.; Chawla, Vardaan; Bolin, Trudy; Clemens, Bruce M.; Cunha, A. F. daCopper zinc tin sulfide (CZTS) is a promising Earthabundant thin-film solar cell material; it has an appropriate band gap of ~1.45 eV and a high absorption coefficient. The most efficient CZTS cells tend to be slightly Zn-rich and Cu-poor. However, growing Zn-rich CZTS films can sometimes result in phase decomposition of CZTS into ZnS and Cu2SnS3, which is generally deleterious to solar cell performance. Cubic ...
