[OLED4-2(Invited)] Efficient Perovskite Light-Emitting Diodes Enabled by Synergetic Device Architecture

Yanqing Li1, Yang Shen1, *Jianxin Tang1 (1. Soochow University (China))

Keywords:Perovskite light-emitting diodes, CsPbBr3, light outcoupling, moth-eye nanostructures

In this work, we demonstrated a facile route was realized by combining bioinspired moth-eye nanostructures and half-ball lens to enhance light outcoupling. As a result, the maximum external quantum efficiency of green perovskite light-emitting diodes was improved to 28.2%, which represented a substantial step toward achieving practical applications of PeLEDs.
