Nature Sustainability, Published online: 13 August 2026; doi:10.1038/s41893-026-01916-6 Practical application of perovskite solar cells requires scalable fabrication in ambient environments. Here the authors introduce PNCC, a hole-transport co-polymer that enables ambient-fabricated devices to achieve certified efficiencies of 33.0% in tandem cells and 23.2% in modules.
