Abstract

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