摘要

The rapid development of perovskite solar cells is bey-ond our imagination.The power conversion efficiency(PCE)of organic-inorganic hybrid perovskite solar cells has reached 25.5％(https://www.nrel.gov/pv/cell-efficiency.html).How-ever,the unsatisfactory stability of hybrid perovskites is an obstacle for their commercialization,which results from the volatile and hygroscopic organic cations[1].Recently,inorgan-ic perovskites(CsPblxBr3-x)are receiving more and more atten-tion due to their good thermal stability[2].Among them,CsPbl2Br is the most popular material for solar cells due to the appropriate Goldschmidt tolerance factor[3,4].
