2D Perovskites In article number 2102236, Jong Hyeok Park, Nam‐Gyu Park, Hyunjung Shin and co‐workers extract photo‐generated holes from 3D bulk perovskites of FAPbI 3 through cyclohexylamonium‐based 2D perovskites. 2D/3D perovskite heterojunction structures are successfully fabricated and the efficient extraction of holes is expressed in this cover picture.
