太阳能光伏技术, 能实现太阳能与电能的高效转换, 是实现人类文明可持续发展的关键绿色能源技术. 其中, 有机无机杂化钙钛矿太阳能电池具有优异的光电特性、低廉的制备成本、高效的转换效率, 已成为该领域的研究前沿. 虽然有机无机杂化钙钛矿太阳能电池的光电转换效率已约高达24%, 但其体系中的有机物组分易受环境中的光、热、潮等因素影响而分解, 致使器件稳定性存在严重的缺陷, 极大地限制了钙钛矿太阳能电池的产业化进程. 因此, 如何制备高效稳定的钙钛矿太阳能电池, 是目前该领域的研究热点与难点, 而发展具有更高环境稳定性的全无机钙钛矿太阳能电池具有重要意义. 本文回顾了近年来全无机钙钛矿太阳能电池领域的研究成果, 重点审视了钙钛矿薄膜的湿法制备工艺, 并探讨了器件在光热稳定性方面的改善, 为进一步推动钙钛矿太阳能电池的实用化进程提供可行性参考.Photovoltaic technology, which can converse solar illumination into electricity, is crucial to the sustainable development of human civilization. Among them, the organic-inorganic hybrid perovskite solar cell (OIPSC) has become a research front due to its excellent photoelectric characteristics, low production cost and high power conversion efficiency (PCE). Although the PCE of OIPSC has exceeded 24%, the organic components in the perovskite system are sensitive to the decomposion caused by either being exposed to light or heated in high temperature environment. The stability defects have greatly limited the commercialization of perovskite solar cells. Therefore, it is urgent to improve the stability of perovskite solar cells, especially to solve the material decomposition problem. All-inorganic perovskite photovoltaic material, composed of all-inorganic elements, exhibits excellent heat and moisture resistance. Therefore, the development of all-inorganic perovskite solar cells is of great significance for solving the current stability problems in perovskite photovoltaics. In this work, we review the recent research progress of all-inorganic perovskite solar cells, discuss the solution approaches to processing all-inorganic perovskite films, and explore the enhancement of device stability. Our work provides a guideline for further promoting the device stability and PCE.
