Scalable Manufacturing and Precise Patterning of Perovskites for Light-Emitting Diodes

Abstract

This review provides a comprehensive exploration of advanced film and patterning fabrication techniques for high-performance perovskite light-emitting diodes (PeLEDs). This review examines both top-down and bottom-up techniques, such as photolithography and inkjet printing to achieve precise patterning of PeLEDs for full-color displays. This review discusses critical challenges, including device stability, scalable manufacturing, and microscale pixel patterning, as well as promising strategies to overcome these obstacles for the commercialization of PeLEDs.
