Abstract
Large area and efficient CsPbBr 3 perovskite light emitting diodes (PeLEDs) were demonstrated by readily commercializable spray-coating method. The PeLEDs with controlled crystal grain size exhibited maximum electroluminescence peak position of ~534 nm, emission spectrum of ~18 nm of full width at half maximum, maximum luminance of 20388 cd/m 2 , maximum current efficiency of 51.0 cd/A, and maximum external quantum efficiency of 11.19%. The large area glass substrate-based rigid PeLED and polymer substrate-based flexible PeLED were also successfully demonstrated. In addition, the PeLEDs with controlled crystal grain size could generate electric power in a daytime like solar cells, which gained power conversion efficiency of 0.43–1.03% at 1 sun condition (AM 1.5 G 100 mW/cm 2 ). • Nanocrystalline CsPbBr 3 perovskite uniform thin-film is prepared by spray-coating. • The smaller crystal grain size is obtained by optimizing the solvent composition. • Large-area and flexible PeLEDs are fabricated by a scaleable spray-coating process. • The PeLEDs can be used as power generator in day time and as display in night time.
