In article number 1901225, Tae‐Woo Lee and co‐workers suggest a strategy to improve the electroluminescence efficiency of Ruddlesden–Popper (RP) phase perovskite light‐emitting diodes by introducing structurally modulated RP‐phase perovskite emitters, which can improve the charge transport ability without hampering the confinement of the electron‐hole pair. The randomly oriented RP‐phase perovskite forces contact between inorganic layers and thereby improves charge transport ability and radiative recombination.
