Operational and Spectral Stability of Perovskite Light-Emitting Diodes
Source abstract
Abstract
As an emerging light source, perovskite light-emitting diodes (PeLEDs) based on metal halide perovskites have witnessed incredible progress in recent years, and device efficiency is considerably enhanced toward the level of practical applications. However, the stability of the PeLEDs is significantly behind that of commercial light sources. It is imminent to considerably improve the operational stability of the device. In this Review, we first analyze the factors that cause device degradation. Then, we describe the research progress in improving PeLEDs’ operational stability via defect passivation, charge balance, and thermal management. Furthermore, the issue of spectral stability is presented. Finally, we discuss the future development directions for achieving high-performing and stable PeLEDs.
