Perovskite Solar Cells In article number 2000197 , Wei‐Fang Su and co‐workers incorporate a cation of acetamidinium (Aa + ) into conventional perovskite layer (MAPbI 3 ). The Aa + cation effectively hinders the ion migration and enhances the long‐term stability of perovskite solar cells. The champion device achieves 20.68% efficiency. More than 80% of initial power conversion efficiency is maintained after 1300 h of 85°C/85 RH% test as encapsulated.
