Nature Communications, Published online: 25 May 2026; doi:10.1038/s41467-026-73620-0 Formamidine-based perovskite solar cells promise high efficiency, but additive-induced deprotonation disrupts precursor stability and device performance. Dong et al. use a hydrolyzing ester additive to regulate proton transfer, stabilizing the precursor and achieve efficient, durable devices.
