Abstract
Treatment of perovskite surface by bidentate ligands molecules N, N'-Dimethyl-1,2-ethanediamine forms a robust chelated lead iodide layer, stabilizing and passivating the perovskite. This enhances carrier lifetime, adjusts surface energy levels, resulting in perovskite solar cells with 25.7% efficiency (certified 25.04%) and >90% efficiency retention after 1000 hours of aging.
