Abstract
The regenerative photo-electrochemical cell comprises a polycrystalline metal oxide semiconductor layer having a substantially monomolecular chromophore layer in a surface zone. The surface of the metal oxide semiconductor layer has a roughness factor of more than 20, preferably more than 200. Photo-electrochemical cells having such metal oxide semiconductors have good monochromatic efficiency using redox systems with iodides or bromides.
