Abstract

AbstractCu2ZnSn(S1−x,Sex)4 (CZTSSe) solid solution films were prepared on Ti foils by means of non‐vacuum, instantaneous, direct synthesis from elemental Cu, Zn, Sn, S, and Se precursor films using microwave irradiation. XRD patterns and Raman scattering spectra show that the resulting films consist of CZTSe crystals. The lattice constants of CZTSSe decreased in direct proportion to the S/(S+Se) ratio almost satisfying Vegard's law. Resulting films were relatively compact and continuous in the inner part.
