Our research group aims at understanding solar energy conversion reactions and interfacial charge transport of semiconductor-based multilayer photoelectrodes. To understand fundamental performance limitations at relevant length scales, an important aspect is the characterization of material properties und stability under realistic operation conditions and at the nanoscale. The results could benefit the realization of efficient and stable photoelectrodes for solar energy conversion.
