Charge separation at nanostructured molecular donor-acceptor interfaces

This project seeks to unravel the electronic structure of conjugated organic molecules on conductive surfaces and at heterointerfaces by means of photoelectron spectroscopy. Specifically, parameters of importance for photovoltaic cells like hole and electron injection barriers, as well as the photovoltaic gap are determined.
