Efficient Inorganic Vapor‐Assisted Defects Passivation for Perovskite Solar Module (Adv. Mater. 22/2023)

Perovskite Solar Modules In article number 2211593, Yang Wang, Yanlin Song, and co-workers propose a strategy of vapor-assisted defect passivation to manage defects in perovskite solar modules. CS2 can strongly coordinate with undercoordinated Pb2+ and passivate iodide vacancy defects, resulting in remarkable enhancement of the device efficiency (25.20% for 0.08 cm2 and 20.66% for 40.6 cm2).
