This paper reports measurements of electrical impedance versus frequency on photoelectrochemical solar cells and metal-insulator-semiconductor junctions using polycrystalline, electrodeposited n-CdSe electrodes. A simple power law in frequency for the photoelectrochemical cell impedance is interpreted in terms of a percolation conduction at the semiconductor-electrolyte interface with use of arguments supported by measurements on this and related systems.
