Abstract—

Polycrystalline Cu₂ZnSn(S_хSe_{1 – х})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(S_хSe_{1 – х})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.

多晶Cu 2 ZnSn（S x Se 1 – x）4固溶体：合成，相组成和光电导损耗动力学

摘要—

多晶的Cu ₂ ZnSn（S _х硒_{1 - х}）_4种固体溶液制备了通过使用单质铜，锌，锡，S和Se的单温度的方法。通过X射线显微分析确定了合成材料的化学组成，并通过X射线衍射和拉曼光谱研究了它们的晶体结构和相组成。使用频时间分辨微波光电导的测量，我们检查了在铜的光生载流子损失动力学的硫和硒含量的影响₂ ZnSn（S _х硒_{1 - х}）₄固溶体。已经表明，硫含量的增加导致形成另外的深水平，其能够充当电子受体。
