Abstract

Read online

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.
