Abstract

Wide bandgap (WBG) perovskites, with an adjustable bandgap and easy solution fabrication process, are prime candidates for top sub-cells in tandem solar cells (TSCs). Their successful integration with narrow bandgap devices has inspired the rapid development of perovskite-based TSCs and has become one of the most promising technologies in photovoltaics. However, several tough issues related to WBG PSCs, such as open-circuit voltage (V_OC) loss and phase separation, impede their further improvement in device efficiency and stability. Hence, through a systematic review on the development of WBG PSCs, the critical problems such as defects, phase segregation, and strain are discussed, and effective solution strategies, including passivation, additive engineering, composition engineering and interface engineering with self-assembled monolayers (SAM) are summarized. This comprehensive review is expected to provide guidance for designing and developing more effective WBG devices.

宽禁带钙钛矿太阳能电池的性能提升策略

宽禁带（WBG）钙钛矿具有可调的禁带和简单的溶液制造工艺，是串联太阳能电池（TSCs）中顶级亚电池的主要候选材料。它们与窄带隙器件的成功集成激发了钙钛矿基TSCs的快速发展，并已成为光伏发电中最有前途的技术之一。然而，与WBG PSCs相关的几个棘手问题，如开路电压（VOC）损耗和相分离，阻碍了它们在器件效率和稳定性方面的进一步提高。因此，通过对WBG psc发展的系统回顾，讨论了缺陷、相偏析和应变等关键问题，并总结了有效的解决策略，包括钝化、增材工程、复合工程和自组装单层（SAM）界面工程。这一全面审查有望为设计和开发更有效的WBG装置提供指导。
