Abstract

One dimensional rod shaped TiO₂ nanostructures were successfully synthesized by a simple non-aqueous, alcoholysis based solvothermal process. Anatase TiO₂ nanorods (TiO₂ NRs) exhibited a surface area of 109.79 m²/g with particle length and diameter of ∼30-50 nm and ∼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%).
