In perovskite solar cells (PSCs) with wide band gaps (∼1.65–1.68 eV), the poor quality of perovskite films due to uncontrolled fast crystallization significantly contributes to the loss in open-circuit voltage (V OC), thereby limiting the further enhancement of silicon/perovskite tandem solar cells (TSCs).To address this issue, we propose a custom-tailored solvent
