Nature Communications, Published online: 22 April 2026; doi:10.1038/s41467-026-72159-4 Perovskite solar cells face efficiency losses in ambient air because their precursors are highly moisture- and oxygen-sensitive. Liu et al. use an ionic-liquid additive to stabilize precursor chemistry, enabling robust processing and high-performance devices.
