A cell including a photoanode consisting of at least one polycrystalline titanium dioxide layer on a conductive substrate, a counter-electrode and an electrolyte positioned between these electrodes, at least one of said electrodes being transparent or translucent. The electrolyte includes an oxidation-reduction system which is liquid at room temperature. The first species of the pair making up the oxidation-reduction system advantageously consists of an electrochemically active salt having a melting point below room temperature, and optionally being dissolved in at least one electrochemically inactive salt also having a melting point below room temperature. |
