%X 钙钛矿太阳能电池因其光吸收效率高、载流子寿命长、晶格缺陷容忍度高、能带可调等优点得到迅速发展，在短短几年内其太阳能转化效率已经达到22.1%。然而，在人们看到钙钛矿太阳能电池广阔发展前景的同时，其铅毒性和不稳定性严重限制了它的应用推广。无机非铅钙钛矿太阳能电池（ABX3、A2BB'X6等）利用Sn、Ge、Bi、Ag等金属取代铅，以Cs、Rb等取代甲胺有希望解决目前钙钛矿太阳能电池的毒性和稳定性问题。本文主要对近几年无机非铅钙钛矿太阳能电池的研究现状做一个分析总结，并对其发展前景进行展望。<br>Perovskite solar cells have undergone rapid development because of their high solar absorption efficiencies, long carrier lifetime and diffusion length, high tolerance to lattice defects, and tunable bandgaps. In the past few years, the solar energy conversion efficiency of the perovskite solar cells has increased to 22.1%. However, despite their promising prospects, as demonstrated by the laboratory-fabricated prototypes, lead toxicity and instability of perovskite solar cells severely impeded their industrialization and applications. Recently, inorganic lead-free perovskite solar cells (such as ABX3 and A2BB'X6), which use Sn, Ge, Bi, Ag, and other metals as replacements for Pb, and Cs and Rb as replacements for methylamine, have been pursued as potential solutions for the toxicity and stability issues. This review highlights the recent research efforts in the development of inorganic lead-free perovskite solar cells and provides a perspective on future developments
