Making from Breaking: Degradation Inversion Enables Vapor-Phase Synthesis of Halide Perovskites in Ambient Conditions

Christophe Ballif, Aïcha Hessler-Wyser, Christian Michael Wolff, Kerem Artuk, Mostafa Rabie Shlaly Bahr Othman, Austin George Kuba

Vapor phase deposition of formamidinium-rich perovskites is hampered by the decomposition of formamidine in the vapor phase. We use the reversibility of this reaction to establish a dynamic equilibrium that enables the vapor-phase synthesis of formamidiniu ...
