The mismatched bilateral bond strength between NiOx and perovskite hinders the development of inverted perovskite solar cells. Here, authors adsorb 1-(benzothiaxole-2-ylthio)succinic acid on NiOx surface for passivating bilateral defects and achieve maximum efficiency close to 27% in stable devices.
