Co-deposited inverted perovskite photovoltaics towards 27% efficiency via vertical redistribution of self-assembled-molecules and in-situ crosslinking

Nature Communications, Published online: 20 April 2026; doi:10.1038/s41467-026-72097-1 Co-deposited perovskite solar cells suffer from self-assemble monolayer (SAM) aggregation that weakens interfacial adhesion and limits performance. Zhuang et al. design an asymmetric SAM and a crosslinking additive to curb aggregation, enabling efficient, stable devices.
