Electricity is generated by oxidizing a carbon-containing fuel in a photoelectrochemical fuel cell via a cyclic oxidation pathway to yield carbon dioxide and water, and collecting the electrons released via the cyclic oxidation pathway to yield a flow of electrons. The cyclic oxidation pathway includes a series of reactions of which is a photooxidation reaction.
