Environmental friendly and low cost materials for photovoltaic applications always gain a keen interest to make them economical with increased performance. Quaternary compounds with I₂- x -IV-VI₄ arrangement offers favorable properties for optoelectronic devices. In this work, we have substituted antimony in the matrix of Cu₂(x)SnS₄ to form Cu₂SbSnS₄ (CATS) nanoparticles, where the effect of Sb substitution was investigated by the change of ratio with four different compositions. Structural properties reveal the incorporation of antimony with different amounts to significantly alter the morphology of CATS between nanosheets and nanoparticles. All samples obtained the optical bandgap between 1.28 eV and 1.35 eV, which is highly suitable for solar cells. CATS results indicate it has the potential to use in photovoltaic and photocatalytic applications.

用于光伏应用的环保且低成本的材料总是引起人们的强烈兴趣，以使其在提高性能的同时变得经济。具有I ₂ -x -IV-VI ₄排列的四元化合物为光电器件提供了良好的性能。在这项工作中，我们在铜₂（x）SnS ₄的基质中取代了锑，形成了Cu ₂ SbSnS ₄（CATS）纳米粒子，其中通过四种不同成分的比率变化来研究Sb取代的影响。结构性质表明掺入了不同数量的锑，从而显着改变了纳米片和纳米颗粒之间CATS的形态。所有样品均获得了1.28 eV至1.35 eV的光学带隙，非常适合于太阳能电池。CATS结果表明它具有用于光伏和光催化应用的潜力。
