One-dimensional TiO2 nanowires were prepared by electrospinning method. The synthesized nanomaterials have been characterized by powder X-ray diffraction, Scanning electron microscopy, Fourier transform infrared spectroscopy, UV–Visible diffuse reflectance spectroscopy and I–V measurements. The solar cell performance was increased with TiO2 nanowires. The best solar cell performance showed a short-circuit current density (Jsc), open-circuit voltage (Voc), fill factor (FF) and efficiency (ɳ) of 8.57 mA/cm2, 0.65 V, 0.62 and 3.45% compared with P25 which shows Jsc, Voc, FF and ɳ of 6.76 mA/cm2, 0.7 V, 0.61 and 2.88% respectively. The charge transfer resistance at TiO2/dye/electrolyte interface was also studied using electrochemical impedance spectrum.
