| 摘 要： | 采用硫化Zn/Sn/Cu金属多层膜的方法制备了太阳电池吸收层用的Cu2ZnSnS4(CZTS)薄膜。用X射线衍射仪、拉曼光谱仪、紫外-可见近红外分光光度计、扫描电镜、能谱仪及数字源表等对薄膜进行了一系列的表征。结果表明制备的CZTS薄膜没有杂相存在并具有标准拉曼峰。薄膜在可见光范围内的吸收系数>104cm-1,同时其光学带隙接近1.5eV。CZTS薄膜具有均匀致密的表面形貌,薄膜元素比例非常接近标准化学计量比。此外,CZTS薄膜呈现显著的光电流响应性能,其光电流的激发和衰减时间分别为0.0736和0.2646s。

| Abstract: | Cu2ZnSnS4(CZTS) film was prepared by sulfurization of Zn/Sn/Cu multilayer.CZTS film’s characterization was carried out by X-ray diffraction,Raman spectrum,UV-Vis-Nir spectrophotometer,scan electron microscope,energy dispersive spectroscopy and digital source meter.The results show that no any other phases were observed and the Raman peaks observed were in accord with the standard Raman perks of kesterite CZTS.The light absorption coefficient of the film was higher than 104cm-1 and its optical band gap was estimated to be about 1.5eV.The surface of CZTS film was compact and uniform and the element ratio was close to the stoichiometric value.Obvious photo current response property of film was observed,and the photo current excitation time and decay time are 0.0736 and 0.2646s,respectively. |
