Abstract : The photoelectrochemical (PEC) performance of single crystal n-Hafniumdisulfide was correlated with capacitance and impedance measurements obtained with the photoanode van der Waals layers oriented either parallel or perpendicular to acetonitrile-based non-aqueous electrolytes, with and without Copper Chloride introduced as an intercalating redox species. For van der Waals layers perpendicular to the electrolyte (i.e., available for copper intercalation) space charge capacitance values of respectively .01 and 1 micro Farad/sq. cm were obtained for the non-intercalated and copper intercalated photoelectrodes. The implications of these experimental observations were discussed in relation to the application of these intercalating photoelectrodes in both liquid non-aqueous and solid polymer electrolyte PEC storage devices.
