In article number 1702960 , Yanlin Song, Mingzhu Li and co‐workers report a simple and reproducible imprinted method to construct light‐trapping with periodic micro‐nano diffraction‐grating structures on a perovskite active layer using optical discs (CD and DVD). Diffracted light is confined within the perovskite absorption layer by total internal reflection when diffraction occurs. The diffraction‐grating perovskite devices achieve a high power conversion efficiency of 19.71%.
