Abstract

Interfacial electron transfer (IET) dynamics have been measured in a series of dye-sensitized metal oxides commonly using in water splitting dye-sensitized photoelectrochemical cells using optical-pump terahertz-probe spectroscopy. The IET dynamics were compared using a model that allows for the relative contributions of injection from the singlet and triplet excited states of the dye to be distinguished. In addition, we present a newly developed method for performing terahertz (THz) measurements under potentiostatic control (i.e., THz spectroelectrochemistry).
