Abstract

Perovskite light-emitting diodes (PeLEDs) exhibited significant potential for application in advanced display technologies and solid state lighting (SSL), owing to their superior photoelectric performance. However, compared with conventional LED technologies, the instability and disparities across various aspects of PeLEDs have emerged as the primary bottleneck hindering their industrialization. This paper systematically reviews the study of PeLEDs' instability and elucidates that the self-reinforcing feedback cycle between ion migration and phase separation constitutes a critical mechanism underlying device performance degradation. To enhance stability, this work discusses material innovation-based strategies such as ion doping, ligand engineering, and dimensional regulation for component optimization. Additionally, structural improvement approaches, including voltage reduction, insertion layers, and thermal management, are analyzed from the perspective of device engineering. By underscoring the significance and urgency of PeLED instability research, this paper aims to provide concrete insights and methodologies to overcome the stability bottleneck of PeLED devices and expedite the practical implementation of high-stability PeLEDs.
