摘要： A photoactive semiconductor mixed metal oxide material comprises a true solid/solid solution of a specific composition of elemental metals and/or metal non-oxide compounds which are soluble or can be made soluble and which are then fired to produce a true solid solid solution of metal oxide compounds providing an effective band gap and or optical response optimally matched to the part of the energy spectrum desired for a particular utilization. A method of producing the true solid solid solution photoactive semiconductor mixed metal oxide material is also disclosed together with photoelectrochemical semiconductor cells for providing electricity, fuel, chemicals and or chemical energy, preferably solar cells, which utilize the photoactive true solid solid solution semiconductor mixed metal oxide material in a bulk or film electrode. Useful electrolytes include liquid, sol, gel systems. The cells can serve for the simultaneous conversion of light energy into electrical energy and thermal energy utilizing a liquid-junction semiconductor photocell (PEC) utilizing a novel photoactive true solid solid solution semiconductor mixed metal oxide material electrode so as to adjust the band gap and or optical response properties of the electrode to be more closely attuned to the major output portion of the solar sprectrum as well as lowering the cost of production and being environmentally solvent. Further disclosed are photoactive n-type and p-type semiconductor film electrodes utilizable in photo-assisted reactions in photoelectrochemical cells and or photovoltaic cells utilizing the true solid solid solutions described above. The photoactive semiconductor film electrodes have a film layer (20) of the true solid solid solution mixed metal oxide dispersed upon a suitable substrate (10) in either one or more coats, the electrode also including some form of electrical connector (30). Finally, photoelectrochemical cells utilizing solid electrolytes comprising monomers or polymers solvated with liquid materials capable of redox chemistry are also disclosed.
