Аннотация:Perovskite solar cells (PSCs) have attracted significant attention due to their high efficiency and potential forlow-cost manufacturing, but their commercialization is strongly impeded by low operational stability. The en-gineering of charge-transport layer materials have been recognized as an effective strategy to improve bothstability and performance of PSCs. Here, we introduce a pyrrolo[3,4-c]pyrrole-1,4-dione-based n-type copolymeras an electron transport material for perovskite solar cells. Using a composite of this polymer with the fullerenederivative [60]PCBM delivered an efficiency of 16.4% and enabled long-term operational stability of p-i-nperovskite solar cells.
