Abstract

Abstract For an interpretation of the pH-dependence of the sensitized photocurrent at semiconductor electrodes, measurements have been carried out on n-type TiO2 and CdS single crystal electrodes. As sensitizing dyes, rhodamine B and 3,3′-diethylthiacarbocyanine iodide which remain stable in a sufficiently wide pH range were used. It has been found that the logarithm of the sensitized photocurrent at TiO2 electrode depends linearly on the pH of the electrolyte solution, whereas the sensitized photocurrent shows practically no pH-dependence at CdS electrode. These observations have been accounted for on the basis of the different pH-dependence of flatband potentials of these semiconductor electrodes.
