In article number 1702235 , Taiho Park and co‐workers demonstrate that the efficiency of a planar‐type perovskite solar cell is increased by the addition of CuI ionic salt to the TiO 2 electron transport layer. Due to the characteristics of CuI (Visualized on the cover as yellow and red spheres), the electrons from perovskite layer (pink octahedra) show fast extraction to TiO 2 layer (blue and purple spheres).
