Selenocyanate Driven Organic Cations Homogenization in Wide‐Bandgap Perovskite

open access: yesAdvanced Energy Materials, EarlyView.
Selenocyanate pseudohalide doping stabilizes 1.66 eV wide‐bandgap formamidinium (FA)‐based perovskite lattices via strong FA+ hydrogen bonding and matched ionic radii. Uniform cation distribution and suppressed ion migration reduces defect losses, delivering >24% single‐junction efficiency and 32.66% perovskite/silicon tandem performance with ...
