SnO2 has been well investigated in many successful state‐of‐the‐art perovskite solar cells (PSCs) due to its favorable attributes such as high mobility, wide bandgap, and deep conduction band and valence band. Several independent studies show the performances of PSCs with SnO2 are higher than that with TiO2, especially in device stability. In 2015, the first planar PSCs were reported with a power conversion efficiency over 17% using a low temperature sol‐derived SnO2 nanocrystal electron transport layer (ETL). Since then, many other groups have also reported high performance PSCs based on SnO2 ETLs. SnO2 planar PSCs show currently the highest performance in planar configuration devices (21.6%) and are close to the record holder of TiO2 mesoporous PSCs, suggesting their high potential as ETLs in PSCs. The main concerns with the application of SnO2 as ETL are that it suffers from degradation in high temperature processes and that its much lower conduction band compared to perovskite may result in a voltage loss of PSCs. Here, notable achievements to date are outlined, the unique attributes of SnO2 as ETLs in PSCs are described, and the challenges facing the successful development of PSCs and approaches to the problems are discussed.

SnO2在钙钛矿太阳能电池中的应用综述
由于SnO 2具有良好的特性，例如高迁移率，宽带隙，深导带和价带，因此已经在许多成功的先进钙钛矿太阳能电池（PSC）中得到了充分的研究。多项独立研究表明，SnO 2的PSC的性能高于TiO 2的PSC ，特别是在器件稳定性方面。2015年，首次报道了使用低温溶胶衍生的SnO 2纳米晶体电子传输层（ETL）的功率转换效率超过17％的平面PSC 。从那时起，许多其他小组也报告了基于SnO 2 ETL的高性能PSC 。氧化锡2平面PSC在平面配置器件中表现出最高的性能（21.6％），接近TiO 2中孔PSC的记录保持者，表明它们在PSC中作为ETL的潜力很大。使用SnO 2作为ETL的主要问题是，它在高温过程中会退化，并且与钙钛矿相比，其导带低得多，可能会导致PSC的电压损失。这里，概述了迄今为止的显著成就，描述了SnO 2作为PSC中的ETL的独特属性，并讨论了PSC成功开发所面临的挑战和解决问题的方法。
