In article number 1901517 , Yan‐Qing Li, Shuit‐Tong Lee, Jian‐Xin Tang, and co‐workers demonstrate a facile and effective light‐extraction scheme using bioinspired moth‐eye nanostructures, which can efficiently release the trapped light in perovskite light‐emitting diodes (PeLEDs). An external quantum efficiency exceeding 28% is achieved in green‐emitting PeLEDs.
