A photoelectrochemical regenerative photovoltaic cell is provided that includes an electrode structure having a semiconductor photoelectrode layer, and a pinhole-free metal oxide layer disposed on the semiconductor photoelectrode layer forming the electrode structure, where the pinhole-free metal oxide layer is less than 10 nm in thickness, where the thickness of the pinhole-free metal oxide layer protects the semiconductor photoelectrode layer from i) oxidation, ii) dissolution, or i) and ii) when in contact with an electrolyte solution, where the pinhole-free metal oxide layer has a band gap that is transparent to solar radiation and provides band offsets that permit facile electron or hole transport between the electrolyte solution and the semiconducting photoelectrode. |
