采用喷雾热解法和硫化法制备了Cu 2 ZnSnS 4（CZTS）薄膜。采用改进的超声喷雾系统在空气气氛下进行喷雾热解。采用高真空溅射法制备了Cu/Sn/Zn/glass、Cu/Sn/Cu/Zn/glass和Sn/Cu/Zn/glass四种叠层金属膜，并对它们进行了硫化处理。与通过硫化堆叠金属膜制成的CZTS膜相比，未观察到具有良好结晶性的喷涂膜生长良好。然而，有人发现，额外的硫化喷涂CZTS膜的应用诱导的结晶度的硫化金属膜的水平有很大的改善。这意味着喷雾热分解与额外的硫化是一个很好的方法，用于制造CZTS薄膜，特别是作为一种低成本的制造技术。采用X射线衍射（XRD）、扫描电子显微镜（SEM）、X射线能谱（EDS）和拉曼光谱对薄膜进行了表征。
We fabricated Cu2ZnSnS4(CZTS) thin films using two different methods, spray pyrolysis and sulfurization of Cu–Zn–Sn metallic films. Spray pyrolysis was carried out under air ambient with modified ultrasonic spray system. Sulfurizations of metallic Cu–Zn–Sn films were done for stacked metallic films, Cu/Sn/Zn/glass, Cu/Sn/Cu/Zn/glass and Sn/Cu/Zn/glass, which were prepared by sputtering method in high vacuum chamber. The sprayed films were not observed to be grown well with good crystallinity, compared with CZTS films made by sulfurization of stacked metallic films. However, it was found that application of additional sulfurization to sprayed CZTS films induced great improvement of crystallinity to the level of the sulfurized metallic films. This implicates that spray pyrolysis with additional sulfurization is a good method for fabrication of CZTS films, especially as a low-cost fabrication technique. All CZTS films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and Raman spectroscopy measurements.
