混合卤化铅钙钛矿太阳能电池（PSC）在过去十年中经历了快速发展，认证效率已达到25.5%。然而，混合卤化铅钙钛矿中有毒铅组分的存在和有机阳离子固有的差的热稳定性阻碍了它们相应的光伏器件的商业应用。因此，制备高效的全无机无铅PSC是一个很有前途的方向。本文综述了无机无铅钙钛矿及其器件的结构和光电性能的研究进展。特别是，提高Cs-Sn钙钛矿的性能和稳定性，以及提高相应器件的光伏性能的策略是突出的。展望了全无机无铅PSC的发展前景和面临的挑战。
Hybrid lead halide perovskite solar cells (PSCs) have experienced a rapid development in the past decade and a certified efficiency up to 25.5% has been achieved. However, the presence of toxic lead component and the inherent poor thermal stability of the organic cations in the hybrid lead halide perovskites obstruct the commercial applications of their corresponding photovoltaic devices. Therefore, fabricating high-efficient all-inorganic lead-free PSCs is a promising direction. This review summarizes the related research progress, which mainly focuses on the structural and optoelectronic properties of inorganic lead-free perovskites and devices. In particular, the strategies for improving the properties and stability of Cs–Sn perovskites, as well as enhancing the photovoltaic performance of the corresponding devices are highlighted. An outlook of challenges and future directions regarding to all-inorganic lead-free PSCs are also proposed.
