The highest power conversion efficiency of perovskite solar cells is beyond 22%. Charge transport layers are found to be critical for device performance and stability. A traditional electron transport layer (ETL), such as TiO2, is not very efficient for charge extraction at the interface, especially in planar structure. In addition, the devices using TiO2 suffer from serious degradation under ultraviolet illumination. SnO2 owns a better band alignment with the perovskite absorption layer and high electron mobility, which is helpful for electron extraction. In this Review, recent progresses in efficient and stable perovskite solar cells using SnO2 as ETL are summarized.

SnO2:钙钛矿太阳能电池的绝佳电子传输层



钙钛矿太阳能电池的最高功率转换效率超过22%。人们发现电荷传输层对于器件性能和稳定性至关重要。传统的电子传输层(ETL),例如TiO 2 ,​​对于界面处的电荷提取不是很有效,尤其是在平面结构中。此外,使用TiO 2的器件在紫外线照射下会遭受严重的降解。 SnO 2与钙钛矿吸收层具有更好的能带对准性和较高的电子迁移率,这有助于电子提取。本综述总结了使用 SnO 2作为 ETL 的高效稳定钙钛矿太阳能电池的最新进展。
