(Science 2017) A Franco-American researchers team has elucidated the origin of the remarkable performances of devices based on layered perovskites for photovoltaic and light emission. This is based on the spontaneous conversion of electron-hole pairs, also called excitons, into free charge carriers via specific states located on the edges of the thin films used in the devices (...)
