Abstract

Abstract

Through a novel solvothermal method, single-crystalline anatase TiO₂ nanorods were prepared using tetrabutylammonium hydroxide (TBAH) as the morphology controlling agent. The obtained TiO₂ nanorods are dominated by a large percentage of {010} facets on the surface. The short-circuit current density J_sc of the dye-sensitized solar cells (DSSCs) made of the TiO₂ nanorods is about 10.9 mA/cm², with the open circuit voltage V_oc and photoelectric conversion efficiency at 0.74 V and 5.75%, respectively. Compared with DSSCs made of commercial P25 TiO₂, the short-circuit current density, fill factor, and photoelectric conversion efficiency of the cell made of the TiO₂ nanorods are increased by 2.83%, 10.94% and 10.58%, respectively. On basis of the material characterizations, the formation mechanisms were discussed preliminarily.
