%X 有机–无机杂化钙钛矿材料中的有机成分造成器件性能衰减是该类光电器件产业化应用中存在的主要挑战，基于铯的全无机卤化物钙钛矿太阳能电池(PSCs)研究对解决这一问题具有重要意义。本文针对无机CsPbI<sub>3？x</sub>Br<sub>x</sub>钙钛矿薄膜，通过调控卤素I、Br的成分来调节无机钙钛矿带隙和光电性能。综合考虑无机钙钛矿器件效率与稳定性后，选取了CsPbIBr<sub>2</sub>作为后续研究的组分，进一步研究了前驱体浓度和钙钛矿膜的退火温度对薄膜形貌、晶相及组装电池光电性能的影响，在基于CsPbIBr<sub>2</sub>的无机钙钛矿太阳能电池中获得了8.14%的效率。<br />
For industrial application of organic-inorganic hybrid perovskite solar cells, the degradation of de-vice performance caused by the organic components in perovskite is one of the main challenges. The research of all-inorganic cesium-based halide perovskite solar cells is one of the most important strategies for solving this issue. This paper focuses on inorganic CsPbI<sub>3？x</sub>Br<sub>x</sub> perovskite thin films. The band gap and photovoltaic performance of inorganic perovskite were adjusted by changing the halogen ratio of I and Br. The composition of CsPbIBr<sub>2</sub> was chosen for subsequent perovskite devic-es by considering the requirements of relatively high efficiency and suitable stability. The influence of the precursor concentration and the annealing temperature of the perovskite film on the film morphology, crystal phase and photovoltaic performance of the assembled cell was further studied. The efficiency of 8.14% was obtained in the inorganic perovskite solar cell based on CsPbIBr<sub>2</sub>.
