The performance of hybrid perovskite-based light-emitting diodes (LEDs) is markedly enhanced by the application of a NiOx 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.
