Solvent strategies toward high-performance perovskite light-emitting diodes

Abstract

Perovskite light-emitting diodes (PeLEDs) have attracted much attention in the past few years due to their excellent photoelectric performance. Owing to the advantages of adjustable bandgaps, high photoluminescence quantum yields, and excellent charge transfer properties, PeLEDs have emerged as next-generation candidates for use in light-emitting devices. However, efficiency and stability issues have always been problems restricting their development. Different approaches such as device structure optimization, interface engineering, solvent engineering, annealing treatment, additive engineering, and humidity control have been recently reported for overcoming the challenges facing PeLEDs. In this review, solvent-based strategies for obtaining high-performance perovskite light-emitting diodes are the main topic of discussion. In addition, an outlook focusing on solvent-based strategies to further enhance the performances of PeLEDs is proposed.
