Perovskite Solar Cells In article number 2000093 , Ming‐Chung Wu, Kun‐Mu Lee, and co‐workers use polyethylene glycol (PEG) as an additive for the perovskite active layer in lead‐reduced perovskite solar cells. The PEG can effectively control the surface morphology of the perovskite film and improve the charge carrier transport. For 10% lead‐reduced perovskite solar cells, a champion power conversion effi ciency of 16.1% is obtained without signifi cant hysteresis.
