论文摘要
<正>Organic-inorganic lead halide perovskite solar cells（PSCs）have been marching rapidly in recent years with power conversion efficiency（PCE）boosting from 3.8%to 24.2%（NREL Best Research-Cell Efficiency Chart,https://www.nrel.gov/pv/cell-effi ciency.html,Accessed April 2019）.However,these solar cells are not stable at high temperatures due to volatile organic cations[1].Allinorganic perovskites with cesium cation like CsPbI1-xBrx present high thermal stabilities[2].By partially replacing I-with Br-,the bandgap for CsPbI1-xBrx can be tuned from 1.73 to 2.36 eV.
