,简称CZTSSe)薄膜太阳能电池因其组成元素地壳含量丰富、低毒等优点受到广泛关注。目前,吸收层的高缺陷密度和器件的低开路电压被认为是限制该类电池效率的两个关键因素。为了突破这两大困境,科研人员发展了阳离子取代方法,即通过引入其他阳离子取代CZTSSe晶格中的铜离子(Cu

),改善薄膜中的有害缺陷、晶体结构、能带结构等性质,从而优化电池器件的性能。为了详细阐述阳离子取代措施在铜锌锡硫硒薄膜电池中的研究进展,本文从等价阳离子取代和不等价阳离子取代两方面进行分类介绍,并总结了各种阳离子取代措施在优化电池性能方面的优缺点。

(CZTSSe) thin film solar cells have attracted much extensive attention
since the constituent elements are rich in earth
low toxic
etc
. At present
high defect density of the absorber layer and low open circuit voltage of device are both considered as two key factors limiting the efficiency of device. In order to break though the two difficulties
the researchers developed the substitutions of Cu

improving the performance of devices. Here
we classify by equivalent and inequivalent cation substitutions to elaborate current research development of CZTSSe thin film solar cells by cation substitution
and summarize their advantage and disadvantage in optimizing performance of devices.
