Wire-based dye-sensitized solar cells using electrodeposited zinc oxide on passivated metals — •Tim Helbig, Melanie Rudolph, and Derck Schlettwein — Justus-Liebig-University Giessen, Institute of Applied Physics, Heinrich-Buff-Ring 16, D-35392 Giessen, Germany

Metal substrates provide good properties as electrode material in dye-sensitized solar cells (DSSC) such as good processability, high conductivity and mechanical flexibility. In order to be used in DSSC the metal has to be inert against the iodine-containing electrolyte used in DSSC. Passivated metals such as tungsten, stainless steel or aluminum are covered with a natural oxide layer providing protection against corrosion and are therefore of interest as electrode materials. Zinc oxide thin films were prepared as porous semiconductor on tungsten or aluminum wires by electrochemical deposition. The indoline dye D149 was adsorbed to the surface of the porous zinc oxide as a sensitizer. The films were studied as a photo anode of a DSSC.
