This work investigates the properties of CFTSSe material synthesized by melt quench technique and subsequent thin film deposition using thermal evaporation method. To study the compositional, structural, morphological and optical properties of the material, various characterization techniques like XRD, SEM, EDS, Raman spectroscopy, FTIR and UV–Vis–NIR spectroscopy have been applied. These studies show that CFTSSe is crystalline in nature and consistent with the stannite structure. Whereas some large density electronic defects have been detected in the lattice. UV visible spectroscopy estimates a high absorption coefficient (>10⁴ cm⁻¹) and optimal band gap of 1.49 eV. Additionally, the properties of CFTSSe are also compared with our previous study of CZTSSe and appeared to have potential to be used in thin film solar cell applications.

这项工作研究了通过熔体淬火技术合成的 CFTSSe 材料的性质，然后使用热蒸发方法进行薄膜沉积。为了研究材料的成分、结构、形态和光学性质，已经应用了各种表征技术，如 XRD、SEM、EDS、拉曼光谱、FTIR 和 UV-Vis-NIR 光谱。这些研究表明，CFTSSe 本质上是晶体，与锡石结构一致。而在晶格中已经检测到一些大密度的电子缺陷。紫外可见光谱估计高吸收系数 (>10 ⁴  cm ^-1) 和 1.49 eV 的最佳带隙。此外，CFTSSe 的特性也与我们之前对 CZTSSe 的研究进行了比较，并且似乎具有用于薄膜太阳能电池应用的潜力。
