TiO2 Nanowire dye-sensitized solar cells Fabricated by Hydrothermal Method

摘要

TiO2 nanowire dye-sensitized solar cells were fabricated by using hydrothenml method. The synthesizing of TiO2 nanowire/nanorod arrays directly on FTO substrate would cause a high conducting loss to solar cells. Through laminating a compact layer between FTO substrate and photonic anode layer, the conducting loss could be effectively prevented. Results indicated that using different concentration of titanium tetrabutoxide would affect the photoelectric conversion efficiency and different producing methods of the compact layer also played an important role to the conversion efficiency.
