“Researchers have made significant progress in the field of perovskite light-emitting diodes (PeLEDs), introducing an in-situ co-evaporation technique to passivate grain boundary defects and suppress trap states, thereby enhancing the photoluminescence quantum yield. This method offers a solution to improve the efficiency and brightness of thermal-evaporated PeLEDs, laying a foundation for their commercial prospects.”
