— Spectral photosensitization is discussed from an electrochemical point of view, as caused by electron transfer from or to excited molecules. General principles for a description of electron transfer processes at semiconductor or insulator electrodes are reviewed and applied to reactions which involve excited electronic states. The conditions for suitable experimental arrangements are characterized. Illustrations for the application of these techniques are given. The examples show spectral sensitization of photocurrents due to electron or hole injection into inorganic or organic solids.
