A regenerating photoelectrochemical cell (1) is disclosed having a first transparent substrate (2) which has thereon a first transparent electrode (6), a second transparent substrate (4) which has thereon a second transparent electrode (8) on which is deposited a first layer (10) of a photoelectrochemically active semiconductor oxide in the form of a porous nanostructure of sintered colloidal particles, the substrates (2, 4) being so disposed in relation to one another as to define a space filled with electrolyte (16), said electrolyte (16) impregnating the said porous structure in a manner such that it is in contact on the one hand with the first transparent electrode (6) disposed on the first transparent substrate (2) and on the other hand with the second transparent electrode (8) disposed on the second transparent substrate (4), and said second transparent substrate also having a second compact continuous semiconductor oxide layer (20) extending between the second transparent electrode (8) and the first semiconductor oxide layer (10).
A regenerating photoelectrochemical cell comprising a first transparent substrate which has thereon a first transparent electrode, and a second transparent substrate which has thereon a second transparent electrode on which is deposited a first layer of a photoelectrochemically active semiconductor oxide in the form of a porous nanostructure of sintered colloidal particles, said substrates being so disposed in relation to one another as to define a space filled with electrolyte, said electrolyte impregnating said porous structure in a manner such that it is in electrical contact on the one hand with the first transparent electrode disposed on the first transparent substrate and on the other hand with the second transparent electrode disposed on the second transparent substrate, and said second transparent substrate also having thereon a second semiconductor oxide layer which is compact, continuous, and extends between the second electrode and the first semiconductor oxide layer.
