✦ Synopsis

When mixtures of dyes with close enough characteristic wavelengths were employed in single cell arrangements, the light absorbing capabilities were found to increase, giving rise to enhanced photovoltages. Multilayer-organic dye photocells, which were fabricated, generated a high photovoltage. These photocells were then investigated as photoelectrochemical cells. In a 10 layer cell arrangement of the type SnO,/lO mM Phenosafranine + 10 mM Brilliant Cresyl Blue + 0.5 M EDTA/Pt, in optical and electrical series, photovoltages as high as 6.4V were recorded. The characteristics of the photoelectrochemical processes and the problems of photocurrent generation are discussed.
