Abstract

Chemical modification of semitransparent electrodes with various dye molecules allows photoassisted electrolysis to occur with visible wavelength excitation and without an optically dense solution of the dye adjacent to the electrode. Linear, multi-electrode stacks of the semitransparent electrodes allow for more efficient capture of light normally lost by transmission. A ratio of photocurrent to photon flux ( n_c n_p) of ca. 1-2% is possible for certain dye modified electrode stacks, when used in the photoassisted oxidation of hydroquinone. Stacks of electrodes with more than one bound dye allow for the use of more of the visible wavelength spectrum than with a single dye.
