Abstract
In this work, we have synthesized 1-dimensional (1D) TiO2 nanofibers (NFs) by using the electrospinning technique for dye-sensitized solar cells (DSSCs) application. The synthesized 1D-TiO2 NFs were characterized by using UV–Visible spectroscopy, Fourier-transform infraredspectroscopy, X-ray diffraction, field emission scanning electron microscope and energy dispersive spectroscopy techniques. The optimized1D-TiO2 NFs were used to develop DSSCs using solution-processable techniques. In this work, we have explored the effect of annealing temperature (450 °C and 500 °C) and dyes (N719 and N350) on the solar cell properties. Our results asserted that the low-temperature annealing process provides good efficiency and N719 dye performs better than N350 dye. In addition to this, the diameter of the TiO2 NFs was varied to investigates its effect on different solar cell properties. The present investigation is helpful to optimize the NFs based DSSCs.
