Dye-sensitized solar cells based on ordered titanate nanotube films fabricated by electrophoretic deposition method

Dye-sensitized solar cells (DSSCs) are fabricated based on ordered titanate nanotube (TNT) films obtained by electrophoretic deposition (EPD) method. Calcination temperatures show a great influence on the performance of TNT solar cells. At 300 degrees C, the cells exhibit very low photo-electric conversion efficiency. At 400 degrees C, the efficiency obviously increases. At 600 degrees C, the cells show the highest efficiency, which is higher than the efficiency of the cells made from commercial-grade Degussa P25 TiO2 nanoparticles (P25). (C) 2009 Elsevier B.V.
