The use of photoelectrochemical cells (PECs) to mediate the direct conversion of optical energy to electricity is receiving widespread attention. Typical PECs consist of an n-type semiconductor photoanode, a counterelectrode and the electrolyte. The key elements are the semiconductor which functions in the dual roles of photoreceptor and electrode, and the electrolyte which must possess the important features of inhibiting the photocorrosion of the semiconductor. A variety of PECs have now been constructed using these principles and the goal of researchers in the field in generally to optimize the efficiency and longevity of such devices. This report discusses a promising avenue to optimizing efficiency involves characterization of the excited state processes governing the semiconductor electrode. Deactivation of the excited electrode to produce photocurrent and, hence, electricity is only one of several decay paths available.
