Summary: Research has found that halide-related surface defects on inorganic halide perovskite can lead to charge recombination and affect the long-term stability of perovskite solar cells. Using density functional theory calculation, it has been verified that iodine interstitials (I-i) have a low formation energy and are easily formed on the surface of all-inorganic perovskite. A specific passivator called 2,6-diaminopyridine (2,6-DAPy) has been screened, which successfully eliminates iodine interstitials, dissociative iodine molecules, and passivates iodine vacancies. This passivation process improves the power-conversion efficiency (PCE) and environmental stability of the perovskite solar cells.
