Abstract

In this work, we focus on the development of red and green perovskite LEDs and investigate the role of ZnO nanoparticle layers as electron transport interfaces. Understanding these materials and interfaces is an important step toward more advanced device architectures, such as stacked and tandem LEDs for improved brightness and color control.
