【 摘 要 】

All-inorganic metal-halide CsPbBr 3 perovskite has emerged as an attractive photovoltaic material for its outstanding environmental stability. However, due to the wide bandgap, the performance of CsPbBr 3 perovskite solar cells (PSCs) is limited, especially for the short-circuit current density ( J SC ). In this issue of Energy & Environmental Materials, Guo et al. employed Nb-doped SnO 2 as electron transporting layers (ETLs), which could greatly improve the J SC of the PSCs based on all-inorganic CsPbBr 3 .
