In this work, the quaternary nanostructured Cu₂ZnSnS₄ (CZTS) thin films were deposited on ITO glass substrates at a temperature of 300${}^{\circ }$C by spray pyrolysis method and the influence of inter-molar concentration variations of copper and zinc on the structural, morphological and optical properties of grown samples was studied. The films were characterized by different sophisticated techniques including X-ray diffractometer (XRD), scanning electron microscopy (SEM), Raman spectroscopy and UV–Vis spectroscopy. The solitary presence of kesterite tetragonal phase with favored orientation along (112) plane is confirmed by XRD patterns and Raman spectroscopy. However, due to the variation in lattice parameters, a moderate shifting in (hkl) planes was observed. SEM micrographs and EDAX analysis showed the uniform morphology of the so-grown CZTS films covered with nanoplates of different sizes and the ionic compositional variation of the precursor solution matches with the elemental variation in the grown samples. A minor nonstoichiometry in chemical composition ratio $[\mathrm{\text{Cu}}]/[\mathrm{\text{Zn+Sn}}]$ from 0.74 to 1.24 was noticed in the films. Optical studies of CZTS films showed that these films possess optical band gap ranging from 1.45$$eV to 1.60$$eV.

在这项工作中，四元纳米结构 Cu ₂ ZnSnS ₄ (CZTS) 薄膜在 300 ℃的温度下沉积在 ITO 玻璃基板上。${}^{\circ }$采用喷雾热解法制备C，研究了铜、锌摩尔间浓度变化对生长样品的结构、形貌和光学性质的影响。这些薄膜通过不同的复杂技术进行了表征，包括 X 射线衍射仪 (XRD)、扫描电子显微镜 (SEM)、拉曼光谱和紫外-可见光谱。XRD 图案和拉曼光谱证实了黄锡锌矿四方相的单独存在，该四方相具有沿 (112) 面的有利取向。然而，由于晶格参数的变化，( hkl）飞机被观察到。SEM 显微照片和 EDAX 分析显示，如此生长的覆盖有不同尺寸纳米板的 CZTS 薄膜具有均匀的形态，并且前体溶液的离子组成变化与生长样品中的元素变化相匹配。化学成分比例较小的非化学计量$[\mathrm{\text{铜}}]/[\mathrm{\text{锌+锡}}]$电影中注意到从 0.74 到 1.24。CZTS 薄膜的光学研究表明这些薄膜的光学带隙范围为 1.45$$eV 至 1.60$$eV。
