Abstract

Defect passivation containing ionic liquids (ILs) on perovskite films has been proven to be an extremely effective strategy for highly efficient perovskite solar cells (PSCs). However, the exact interaction mode between the ILs and perovskite crystals and the microcosmic mechanism of the structures of ILs on the devices are not clear. Here, we incorporated an amine-functionalized IL for effective defect passivation on the perovskite films. The amine-functionalized IL interacts with Pb 2+ and X – in perovskite crystals, which can effectively passivate defects and regulate the perovskite crystal growth, forming high-quality perovskite films. The microcosmic mechanism investigation reveals that the effective defect passivation and defect migration suppression due to the amine-functionalized IL facilitate the improvement of the photovoltaic performance of the PSC devices.
