WebJan 5, 2014 · CZTS films with different compositions were grown from stacked-layer precursors. • The band-gap energy varies from 1.48 to 1.63 eV as the [Sn]/ [Cu] ratio increases. • The Zn content seems not to be a critical parameter for the optical properties. • PDS data show an increase of the sub-gap absorption as the Sn content is reduced. • WebMar 15, 2010 · We show that CZTS is the thermodynamically stable phase for a rather small confined domain of chemical potentials. Even slight deviations from the optimal growth conditions will therefore result in the formation of other sulfidic precipitates, including ZnS, Cu2SnS3, SnS, SnS2, and CuS.
