Stability of Perovskite Light‐Emitting Diodes: Existing Issues and Mitigation Strategies Related to Both Material and Device Aspects (Adv. Mater. 43/2022)

Perovskite Light-Emitting Diodes Although the efficiency of perovskite light-emitting diodes (LEDs) has reached commercial requirements, their operational lifetime is still challenging. In article number 2205217, Xiaoyu Zhang, Andrey L. Rogach, Xuyong Yang, and co-workers review recent advances in the lifetime of perovskite LEDs, the origins of instability in perovskite LEDs, and strategies to improve the stability on both material and device aspects.
