Abstract

Both aligned titanium dioxide (TiO,) nanorods and nanoflowers were deposited on the fluorine-doped SnO, transparent conducting glass substrate by the hydrothermal method. Characterizations of the hybrid dye-sensitized solar cell (DSC) with rutilephased TiO, nanorods and nanoflowers were performed such as surface morphology, structural property, dye-adsorption and energy conversion efficiency of the device. In the hybrid DSC preparation, both TiO, nanorods and nanoflower, platinum (Pt) ruthenium dye N719 and DPMll electrolyte were used as photoelectrode, counter electrode, dye solution and liquid electrolyte, respectively. In order to enhance the porosity of TiO, film, 0.001 M of polyethylene glycol (PEG) were added in the preparation of rutile-phased TiO, nanorods and nanoflowers. The thicknesses of the TiO, nanorods- and nanoflowers-layers are 5 pm and 15 pm, respectively. Lastly, I-V measurement of the hybrid DSC was done under the light intensity of 100 mW/ cm2. It was found from the results that open circuit voltage (VOC), short circuit current density (JSC), fill factor (ff) and energy conversion efficiency (q) were 0.786 V, 7.753 mAlcm2, 0.537 and 3.27%, respectively.
