One-dimension (1D) TiO2 nanorods (TiO2-N) has been fabricated via electro-spinning method. The composites of 1D TiO2-N and graphite nanosheets, termed as (TiO2-N/G-N), have been obtained by the physical doping method. The structure and properties of TiO2-N and TiO2-N/G-N have been characterised by scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and Raman spectrum. Dye-sensitised solar cells devices with TiO2 nanoparticles, TiO2-N and TiO2-N/G-N as the mesoporous scaffolds have been developed and investigated, respectively. Device 2 based on TiO2-N scaffolds showed short-circuit current (J sc) of 5.57 mA·cm−1, open-circuit voltage (V OC) of 0.68 V, filling factor of 0.75, and the power conversion efficiency of 2.85%, respectively. Compared with device 2, device 3 based on TiO2-N/G-N exhibited reduced photovoltaic properties.
