含铯卤化钙钛矿的研究进展

Research progress of cesium halide perovskite

综述含铯卤化钙钛矿的研究现状,包括卤化铯铅钙钛矿和无铅卤化钙钛矿。卤化铯铅钙钛矿具有优良的荧光、光电转换性能,在太阳能电池、LED、激光器、光电探测器的应用中备受关注。但由于铅具有毒性并且可在人体内积累,限制了卤化铯铅钙钛矿的实际应用。无铅卤化钙钛矿利用Sn、Bi、Ag等金属取代铅,可以有效解决卤化铯铅钙钛矿的毒性和稳定性问题,但目前存在荧光、光电转换性能差的问题。认为无铅卤化钙钛矿的应用前景比卤化铯铅钙钛矿更广阔,为未来含铯卤化钙钛矿的制备和性能研究提供参考。

This paper reviews the development of cesium halide perovskite, including cesium lead halide perovskite and lead-free halogenated perovskite. Cesium lead halide perovskite has been attracted much attention in the fields of solar cells, LED, lasers and photodetectors due to its excellent fluorescence property and photoelectric conversion properties. However, the severe toxicity of lead and its accumulative nature in the human body can be a great hindrance to practical applications of cesium lead halide perovskite. Recently, lead-free halide perovskites, which use Sn, Bi, Ag and other metals as replacements for Pb, have been pursued as potential solutions for the toxicity and stability issues. But there are currently problems with poor fluorescence performance and photoelectric conversion performance. It is considered that the application prospect of lead-free halide perovskite is broader than that of lead halide perovskite. This review can provide a valuable reference for the research of cesium halide perovskite in the future.
