Exciton localization in solution-processed organolead trihalide perovskites
Abstract
The recombination dynamics of photogenerated carriers in organolead trihalide perovskites are not well understood. Here, He et al.report that the recombination of photogenerated carriers in solution-processed methylammonium-lead-halide films is dominated by excitons weakly localized in band tail states.
