Air-processed efficient and pure green perovskite LEDs based on a PVP-modified NiOx interface layer

Abstract

Perovskite light-emitting diodes (PeLEDs) suffer from moisture instability, which hinders their commercialization. In this study, by employing PVP-modified NiOx films, perovskite films with improved quality and reduced trap density were obtained. The champion device achieved an EQE of 16.05%, marking the highest performance of air-processed devices reported to date.
