Atomistic mechanisms of guanidinium chloride passivation for suppressing ion migration and environmental degradation in MAPbI 3 and FAPbI 3 perovski
Annafi Ado Yaro, Waranchit Ruengsrisang, Non ThongprongGACl passivation suppresses iodide migration, defect formation, moisture adsorption, and oxygen-induced degradation in MAPbI 3 and FAPbI 3 . DFT calculations reveal the synergistic roles of GA⁺ and Cl⁻ in enhancing perovskite stability.
