TiO2 nanorod arrays were synthesized through the one-step hydrothermal process. The influence of deionized water to the morphology of nanorod arrays instead of absolute ethyl alcohol as precursor was also investigated. The results showed that a layer of TiO2 microsphere can be synthesized on the top of the nanorod arrays, which serve as the basic unit for the growth of microsphere and finally result in complex TiO2 nanorod arrays film. The XRDand TEMresults suggeste that the nanorod arrays film is consisted of single-crystalline TiO2with tetragonal rutile phase structures. After the assembling of dye sensitized solar cells with the as-synthesized samples, the open-circuit voltage and short-circuit current density and fill factor were measured out as Voc=0.63 V, Jsc=10.9 mA·cm-2 and FF=56.3%, respectively. The energy conversion efficiency (η) is approximately 4.1%.
