Enhancing perovskite detector performance via bias-induced aging: a reproducible and universal approach

Perovskite RTSDs remain limited by reproducibility. We report a universal reverse-bias aging protocol that drives halogen migration and self-heals bromine Frenkel defects, lowering dark current and boosting charge collection efficiency. Validated on hundreds of APbBr₃ single crystals from multiple sources, it delivers reproducible, near state-of-the-art (2%) energy resolution and a transferable recipe.
