摘要：

Polycrystalline Cu2ZnSn(SxSe1-x)(4) solid solutions have been prepared by a single-temperature method using elemental Cu, Zn, Sn, S, and Se. The chemical composition of the synthesized materials has been determined by X-ray microanalysis and their crystal structure and phase composition have been studied by X-ray diffraction and Raman spectroscopy. Using frequency-time-resolved microwave photoconductivity measurements, we examined the effect of sulfur and selenium content on photogenerated current carrier loss kinetics in the Cu2ZnSn(SxSe1-x)(4) solid solutions. An increase in sulfur content has been shown to result in the formation of additional deep levels, capable of acting as electron acceptors.
