Interfacing pristine BiI3 onto TiO2 for efficient and stable planar perovskite solar cells
Abstract
BiI3 has been proved to be an effective interface modifier in PSCs. A champion efficiency up to 17.79% was achieved for the optimized PSCs. The optimal PSCs showed excellent reproducibility and stability.
