Lead (Pb)‐based perovskite solar cells (Pb‐PSCs) have been recorded with a fascinating power conversion efficiency (PCE) of 25.5%. However, the presence of toxic Pb in the perovskite absorber material hinders the commercial aspects of Pb‐PSCs as a promising and efficient new generation of solar cells. Fortunately, theoretical calculations have predicted that tin (Sn)‐based perovskite solar cells (Sn‐PSCs) could have superior performance comparable to the Pb‐PSCs. Recently, many approaches have been reported for developing efficient Sn‐PSCs but yet they have shown the best PCE of 13.24%. This low PCE compared to Pb‐PSCs might be because Sn‐PSCs have been approached in the same way as Pb‐PSCs. However, from a chemistry viewpoint, the understanding of Sn‐PSCs might be very different from that of Pb‐based ones. Herein, the fundamental knowledge of the chemistry and coordination chemistry of SnII compounds and their structural properties is described. Then, an insight is provided into understanding the recent trends of Sn perovskite formation using various Lewis base additives in the precursor solution and incorporation as a cation in the perovskite lattice. Finally, the influence of utilizing Lewis base additives on the device dynamics is discussed.

高效卤化锡钙钛矿太阳能电池：钙钛矿膜形成过程中锡（II）化合物的化学及其与路易斯碱添加剂的相互作用
记录的基于铅（Pb）的钙钛矿太阳能电池（Pb-PSC）的引人入胜的功率转换效率（PCE）为25.5％。但是，钙钛矿吸收剂材料中有毒的Pb的存在阻碍了Pb-PSC作为有前途和高效的新一代太阳能电池的商业应用。幸运的是，理论计算已经预测，基于锡（Sn）的钙钛矿太阳能电池（Sn-PSC）可以具有与Pb-PSC相当的性能。最近，已经报道了许多开发高效Sn-PSC的方法，但它们显示出13.24％的最佳PCE。与Pb-PSC相比，PCE较低的原因可能是因为Sn-PSC的处理方法与Pb-PSC相同。但是，从化学角度来看，对Sn-PSC的理解可能与对基于Pb的PSC的理解有很大不同。在这里描述了II化合物及其结构性质。然后，提供了一个洞察力，以了解在前体溶液中使用各种路易斯碱添加剂并将其作为阳离子掺入钙钛矿晶格中形成钙钛矿的最新趋势。最后，讨论了使用路易斯碱添加剂对器件动力学的影响。
