摘要：

One dimensional rod shaped TiO2 nanostructures were successfully synthesized by a simple nonaqueous, alcoholysis based solvothermal process. Anatase TiO2 nanorods (TiO2 NRs) exhibited a surface area of 109.79 m(2)/g with particle length and diameter of similar to 30-50 nm and similar to 10-15 nm (from SEM data), respectively. The photovoltaic performance of TiO2 nanorods based electrode was investigated in the dye-sensitized solar cell (DSSC). The device based on TiO2 NRs electrode exhibited an excellent short-circuit current density (J(sc)) of 17.75 mA cm(-2) and an open-circuit voltage (V-oc) of 0.75 V under 1 Sun AM 1.5 G solar light. Due to high dye loading, good light harvesting and fast electron transport, the optimal conversion efficiency (9.21%) of the DSSC fabricated from TiO2 NRs was significantly higher than that of the commercial DP-25 TiO2 nanoparticles based cell (6.43%).
