Abstract

Abstract : In this review, the morphology, composition and microstructure of buried interface are discussed, and the effective passivation strategies and corresponding mechanisms are summarized systematically. Abstract : Emerging perovskite solar cells (PSCs) have evolved rapidly in recent years, and their efficiency has been substantially boosted from the initial 3.8% to certified 25.73% now, showing great application potential. Therefore, they have received extensive attention from both industry and academia. However, there is still a certain gap between this value and its theoretical efficiency. In addition, long-term stability is a major challenge hindering its commercial applications. The modification of the heterojunction interface in PSCs, especially buried interface passivation, is crucial to further improve device efficiency and stability. In this review, the impacts of the morphology, composition, microstructure and other characteristics at the buried interface on PSC performance are systematically investigated. Moreover, proposed strategies and corresponding mechanisms for effective buried interface passivation are summarized, looking forward to further promoting the device performance by providing reference and guidance for designing and developing more effective passivation strategies.
