摘    要:采用磁控溅射和后续硒化退火处理的方法在钛箔衬底上制备了柔性CZTSSe薄膜太阳能电池。利用X射线衍射、拉曼光谱仪和扫描电子显微镜等研究了不同硒化温度对于CZTSSe薄膜的物相、成分、表面形貌以及对太阳电池性能的影响。结果表明,580℃硒化温度下制备的CZTSSe薄膜的结晶质量和致密度最好,表现出贫铜富锌的化学元素比例,并且该温度下制得的柔性薄膜太阳能电池性能相对最高,其光电转换效率达到2.27%。

关 键 词:CZTSSe薄膜  柔性太阳能电池  硒化温度

Abstract:A flexible CZTSSe thin film solar cell was fabricated on a titanium foil substrate by magnetron sputtering and subsequent selenization annealing treatment.The effects of different selenization temperatures on the composition,phase,surface morphology and solar cell performance of CZTSSe films were studied by X-ray diffraction(XRD),Raman spectroscopy(Raman)and scanning electron microscopy(SEM).The results show that the CZTSSe film prepared at 580℃selenization temperature had the best crystal quality and density,showing that the proportion of chemical elements was Cu-poor and Zn-rich.And the flexible thin-film solar cell produced at this temperature has the best performance with the highest conversion efficiency of 2.27%.
Keywords:CZTSSe thin film  flexible solar cell  selenization temperature
