Deskripsi
Light-emitting diodes based on halide perovskites have made remarkable progress but their stability is the bottleneck. Here Miao et al. show 14% quantum efficiency at a current density of 300 mA cm-2 and 23.7 hr lifetime under a current density of 100 mA cm-2, making it promising for actual application.
