Potassium Iodide-Modified Lead-Free Cs<sub>3</sub>Bi<sub>2</sub>I<sub>9</sub> Perovskites for Enhanced High-Efficiency Solar Cells

Lead-free, bismuth-based perovskite solar cells (PSCs) are promising, non-toxic, and stable alternatives to lead-based PSCs, which are environmentally harmful and highly unstable under deprived air conditions. However, bismuth-based PSCs still suffer from low-power-conversion efficiency (PCE) due to...
