摘　　要：在全球能源危机与“双碳”背景下,钙钛矿太阳能电池(PSCs)吸引了全球范围的研究关注,正处于商业化的风口浪尖,但退役PSCs中铅卤化物钙钛矿(LHP)的处理尚未得到充分考虑.研究人员探索了以选择性溶解为基础的溶液回收工艺,即采用有效的溶剂溶解LHP及其降解产物卤化铅并将其回收.基于此,首先介绍了LHP的晶体结构和Pb毒性,以及PSCs的结构和退役PSCs的拆解方法,总结了LHP的溶解度预测方法和低危害溶剂的筛选方法,综述了LHP的溶液回收进展.最后,提出了未来该领域的研究方向,为PSCs的商业化和可持续发展奠定了基础.In the context of global energy crisis and“double carbon”,perovskite solar cells(PSCs)have attracted worldwide research attention.PSCs are on the cusp of commercialization,but the disposal of lead halide perovskite(LHP)in decommissioned PSCs has not been adequately considered yet.A solution recovery process based on selective dissolution has been explored,which requires effective solvents to dissolve both LHP and its degraded lead halide salts and then recycle them.Herein,the crystal structure and Pb toxicity of LHP,as well as the structure of PSCs and the dismantling of decommissioned PSCs are introduced in this review.The solubility prediction methods of LHP and selection methods of low-hazard solvents are summarized.The research progresses are overviewed.Finally,the future research direction of this field is proposed.This work lays the foundation for the commercialization and sustainable development of PSCs.
