Abstract

We demonstrate the enhanced performance of perovskite light-emitting diodes (PeLEDs) using a solution-processable MoO₃ and PEDOT:PSS (PEDOT:MoO₃) composite layer as the hole transport layer (HTL). The PEDOT:MoO₃ composite layer presents improved hole injection through a reduction in the contact barrier between the HTL and the CH₃NH₃PbBr₃ layer and enhanced crystallinity of the perovskite film. The optimized PeLEDs with the PEDOT:MoO₃ composite film showed enhanced external quantum efficiency (EQE) and maximum luminous efficiency, compared to a PeLED using a pristine PEDOT:PSS layer.
