Abstract:In this study, we introduce a novel strategy to improve the productivity of perovskite light-emitting diodes (PeLEDs) by incorporating a KBr interface layer alongside PEDOT:PSS as the hole transport layer (HTL). This innovative approach enables the creation of a standard-red perovskite film emitting light precisely at 630 nm. Our investigation demonstrates that optimizing the concentration of the KBr modified layer (10 mg ml−1), in conjunction with an ethylene glycol (EG)-doped PEDOT:PSS electrode, promotes th… Show more
