Abstract: ?One-dimensional (1D) nanostructured metal oxides have attracted much attention because of their unique properties and potential applications in electronics, photonics and other related areas. The electrospinning technique provide a simple, cost-effective approach for producing polymeric and inorganic nanofibers within a broad range of diameters, from tens of nanometres to a few micrometres according to the selection of the processing parameters. Physical treatment process is shown to enhance the adhesion of TiO2 nanofibers electrospun onto fluorine-doped tin oxide substrates for use in dye-sensitized solar cells. We have evaluated the cell efficiency for J-V characteristic curves by solar simulator. We have found that the best performance is achieved by hot-pressing at 14 MPa. Specifically, a current density of approximately 8.96 mA/cm2, an opencircuit voltage of about 0.82 V, a fill factor close to 72%, and an energy conversion efficiency of approximately 5.33% were all achieved by this process.
