Abstract

Beneficial effects are demonstrated by PbI₂ incorporated into perovskite materials as a light absorber in solar cells. The PbI₂ distributed into the perovskite layers leads to reduced hysteresis and ionic migration, and enables the fabrication of remarkably improved solar cells with a certified power conversion efficiency of 19.75% under air-mass 1.5 global (AM 1.5G) illumination of 100 mW cm^-2 intensity.
