Summary:The theory of the operation of the ideal photogalvanic cell for solar energy conversion is described and the crucial kinetic characteristics that the system must possess are deduced for the homogeneous kinetics, the mass transfer and the electrode kinetics. Existing iron-ruthenium and iron-thionine systems are discussed with respect to the ideal characteristics. In the case of the iron-ruthenium system the kinetics of the thermal back reaction are too rapid and the cell does not have differential electrode kinetics. The iron-thionine system satisfies many of the criteria. A thionine-coated electrode possesses the necessary differential electrode kinetics. Sulphonated thionine is to be preferred to ordinary thionine in that it is more soluble. The performance of the iron-thionine cell with respect to the ideal cell is analysed and discussed.
