Bimolecular Amines Vapor Passivation for Efficient Perovskite Solar Cells Based on Blade-Coated FAPbI3

Formamidinium lead triiodide (FAPbI3)-based perovskite solar cells (PSCs) are highly promising due to the optimal bandgap and high efficiencies but suffer from instability and performance-limiting defects. Conventional solution-based passivation methods...
