Abstract

High-quality electron transport layers (ETLs) are essential for stable and efficient perovskite solar cells (PSCs). Metal sulfides (MSs) are considered potential candidates for ETLs due to their high carrier mobility, low cost, and favorable chemical and physical stability. The quality of the MS films plays important role in the photovoltaic performance of PSCs. However, few reports focus on the relative preparation, characteristics, and corresponding mechanisms of MS-based ETLs. In this review, MS-based ETLs are summarized according to their preparation strategies and the mechanism. We hope that this review can help others understand the intrinsic phenomena of MS-based ETLs and motivate further investigations.

摘要

高质量的电子传输层（ETL）对于稳定且高效的钙钛矿太阳能电池（PSC）至关重要。金属硫化物（MS）因其高载流子迁移率、低成本以及良好的化学和物理稳定性而被视为ETL的潜在候选材料。MS薄膜的质量对PSC的光伏性能起着重要作用。然而，很少有报道关注基于MS的ETL的相关制备、特性及相应机制。在本综述中，基于MS的ETL根据其制备策略和机制进行了总结。我们希望本综述能帮助其他人理解基于MS的ETL的内在现象，并激发进一步的研究。
