Recently, a groundbreaking study emerged from a collaborative effort between a research team led by Professor Xu Jixian at the University of Science and Technology of China and Professor Michael D. McGehee from the University of Colorado Boulder in the United States. Their focus was on dual-function perovskite photovoltaic-light-emitting diode (PV-LED) devices, and they have achieved a significant breakthrough. The team ingeniously introduced a porous embedded light management structure, termed e-Al₂O₃, which seamlessly integrates interface passivation with optical regulation capabilities. This innovative structure effectively addresses the inherent conflict between luminescence and photovoltaic performance in perovskite diodes, paving the way for a synergistic enhancement of both high-efficiency solar cell and high-efficiency light-emitting diode functionalities within a single device. The pertinent research findings have been duly published.
