Perovskite Solar Cells In article number 2100257 , Ming‐Chung Wu, Kun‐Mu Lee, and co‐workers demonstrate an approach where two‐dimensional g‐C 3 N 4 is applied as a template for controlling the nucleation of the perovskite active layer. Adding the urea‐polymerized g‐C 3 N 4 into the perovskite active layer allows for a uniform surface morphology and a reduced trap density. Over 20% power conversion efficiency of perovskite solar cells with superior stability was achieved by the unencapsulated perovskite solar cells with g‐C 3 N 4 .
