Abstract

Solar Energy Harvesting In article number 2304343, Paulina Plochocka, ErminMalic, and co-workers show that excitons in layered perovskites become trapped in emissive high-energy states even at low temperatures, due to a phonon-bottleneck. This buildup of excitons is like a volcano, erupting at high enough temperatures, allowing bright excitons to cool and relax down to their dark ground state.
