摘　　要：采用溶胶—凝胶法和旋涂技术在FTO玻璃衬底上制备了Cu2ZnSnS4(CZTS)前驱体薄膜,在氩气氛围中退火后获得Cu2ZnSnS4薄膜.利用X射线衍射仪(XRD)、拉曼光谱仪(Raman)、扫描电子显微镜(SEM)、紫外—可见分光光度计(UV-VIS)对样品进行表征分析结果表明:450℃退火后的样品为纯相的Cu2ZnSnS4,样品的晶粒尺寸较大,禁带宽度接近太阳光谱的禁带宽度.Cu2ZnSnS4 （CZTS） precursor was obtained from a sol-gel which consists of copper chloride, zinc chloride, tin chloride and thiourea. The spin-coating was used to deposit CZTS precursor on FTO glass substrates, the films were annealed in a argon atmosphere. The sample characterizations were analyzed by x-ray diffraction （ XRD ） , Raman scattering （ Raman ） , scanning election microscopy （ SEM ） and UV-visible-infrared spectrophotometer （UV-VIS）. The results show that there is no other diffraction peak in the 450℃ sample except for CZTS. The sample has larger grain size and close to solar spectrum band gap.
