The performance of hybrid perovskite‐based light‐emitting diodes (LEDs) is markedly enhanced by the application of a NiO x electrode interlayer and moderate methylamine treatment. A hybrid perovskite‐based LED exhibits a peak luminous efficiency of 15.9 cd A −1 biased at 8.5 V, 407.65 mA cm −2 , and 65 300 cd m −2 , showing a distinctive impact for future applications.
