Understanding ultrafast dynamics of photon-to-charge conversion is paramount for optimising light-harvesting systems. Here, the authors use femtosecond time-resolved X-ray photoemission spectroscopy to reveal specific charge separation sites and monitor free charge formation in a model donor-acceptor system.
