Abstract:	摘要： 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 109.79m2/g with particle length and diameter of ~30–50nm and ~10–15nm (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 (Jsc) of 17.75mAcm−2 and an open-circuit voltage (Voc) of 0.75V under 1Sun AM 1.5G 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%). •Tiny TiO2 nanorods with high surface area were prepared by simple solvothermal method.•The obtained TiO2 nanorods (TNR) were applied in DSSC as photoanode and compared with DP-25 commercial TiO2.•The higher efficiency of 9.21 % was obtained for TiO2 nanorod based DSSC than DP-25 TiO2 based device.•TNR based photoanode provide enhanced dye adsorption, better electron transport and efficient light harvesting capacity. 出版者： Elsevier B.V 出版日期： 2014-08-15 出處： Materials letters, 2014-08, Vol.129, p.149-152 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2014 Elsevier B.V. 識別號： ISSN: 0167-577X 識別號： EISSN: 1873-4979 識別號： DOI: 10.1016/j.matlet.2014.04.193
