Nature Communications, Published online: 18 May 2026; doi:10.1038/s41467-026-73210-0 Tin-lead perovskites enable tandem devices to surpass the Shockley-Queisser limit, but oxidation of tin severely degrades film quality and performance. Jiang et al. stabilize bulk and surface with two natural antioxidants, boosting both single- and tandem-device efficiency and stability.
