Title: Stable low-bandgap Pb-Sn binary perovskites for tandem solar cells

A low-bandgap (1.33 eV) Sn-based MA 0.5FA 0.5Pb 0.75Sn 0.25I 3 perovskite is developed via combined compositional, process, and interfacial engineering. It can deliver a high power conversion efficiency (PCE) of 14.19%. Lastly, a four-terminal all-perovskite tandem solar cell is demonstrated by combining this low-bandgap cell with a semitransparent MAPbI 3 cell to achieve a high efficiency of 19.08%.
