The performance of porous sensitized semiconductor electrodes depends on both the quality of the deposited films and the electrode properties of the substrate material in contact with the active electrolyte needed for dye- sensitized solar cells. In this study we varied the substrate metal to study its electrode properties in contact with iodine- containing organic electrolytes. The electrodes were also used as substrates for the deposition of porous zinc oxide by electrochemically induced crystallization reactions. Zinc oxide serves as sensitized wide-bandgap semiconductor and properties of the obtained electrodes in dye- sensitized solar cells will be discussed.
