英文摘要Bismuth-based perovskites are promising candidates for lead-free and air-stable photovoltaics. However, the poor surface morphologies and high exciton binding energy of the bismuth-based perovskites have limited their performances. Herein, the density functional theory calculations unveil that CsBi3I10 possesses favorable optoelectronic properties such as a narrow bandgap, a small effective mass, and relatively high electron mobility. To tackle the poor-surface morphology problem, the high-quality CsBi3I10 films are fabricated via gas-assisted spin-coating and solvent vapor annealing in ambient conditions. Using the [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) as the electron acceptor, an optimized inverted CsBi3I10/PCBM bulk-heterojunction structure enables a high power conversion efficiency of 1.18% among the CsBi3I10-based perovskite solar cells. The approach exemplified in this work could be useful for designing the high-performance Bi-based lead-free perovskite solar cells.
