Light-Responsive Lipoic Acid Strategy for Suppressing Photo-Induced Phase Segregation in Wide-Bandgap Perovskites via Reactive Iodine Species Regulation

Wide-bandgap (WBG) perovskite is promising candidate for tandem device, yet its tendency toward light-induced phase segregation poses a critical challenge. To address this challenge, we propose a light-responsive lipoic acid...
