Enhanced sensitized photoelectrochemical effects are observed upon dispersal of croconate violet, an anionic pseudooxocarbon dye, in an adherent polymer coating (poly(4-vinylpyridine)) on a highly doped tin oxide electrode. Benzoquinone, functioning as a supersentizer, enhanced cathodic photocurrent generation by an order of magnitude. Characteristics of a photoelectrochemical cell employing such a dye-loaded polymer electrode have been investigated. Evidence is presented that dye-loaded polymer coating can mediate electron transfer between the electrode surface and dissolved redox couple.
