随着化石燃料的日益消耗以及环境污染的问题愈发严重，人们迫切需要开发可持续发展的清洁能源。太阳光作为一种容易获得的清洁能源自然获得了人们的青睐，人们利用各种半导体光电材料，充分利用太阳能。有机无机杂化钙钛矿由于其优异的光电性能，近年来吸引了越来越多人的关注，特别是基于MAPbI3/FAPbI3的太阳能电池已经取得了媲美商业用硅太阳能电池的效率。然而铅的毒性以及钙钛矿的水氧稳定性一直是困扰钙钛矿太阳能电池的商业应用的问题。寻找具有高效稳定的无铅钙钛矿材料成了人们亟待解决的问题。铋作为铅在元素周期表中相邻元素，可视作代替铅的有效材料之一，然而相关铋基钙钛矿电池的研究都取得了较低的电池效率，铋基钙钛矿相关的光电性能探究还十分有限。有机无机钙钛矿由于引入了有机组分，导致其成分具有更多的选择性。通过选择各种其他的胺形成的铅卤钙钛矿也有了很多的应用，然而相关有机无机铋卤钙钛矿的研究还十分有限，相关研究主要集中在MA3Bi2I9薄膜钙钛矿电池上。

With the increasing consumption of fossil fuels and the growing environment pollution, there is an urgent need to develop sustainable clean energy. Organic-inorganic hybrid perovskites have attracted more and more attention in recent years due to their excellent optoelectronic properties. It's important to note that the solar cells based on MAPbI3 or FAPbI3 have high photoelectric conversion efficiency, compared with traditional silicon solar cells. However, the potential toxicology issue of lead became a problem that hinders the commercial applications of perovskite solar cells. And the stability of these materials also became a bottleneck. So that, it’s urgent for us to find the new lead-free perovskite materials to replace lead halide perovskites. As a adjacent element of lead in the periodic table, bismuth can be regarded as the effective substitution of lead in perovskite materials. According to the recent research, the bismuth-based perovskite solar cells all achieved lower efficiency, and the exploration of optoelectronics based on bismuth perovskite is still very limited. Organic-inorganic perovskites have more diversity due to the introduction of organic components. Although lead-halide perovskites formed by various other amines have also been used in many applications, the research on organic-inorganic bismuth halide perovskites is still very limited, and related research is mainly focused on MA3Bi2I9 thin film perovskite solar cells.
