Abstract

In this study, TiO₂ nanofibers (NFs) have been synthesized by a simple and cost-effective electrospinning method. The diameter of TiO₂ NFs has been controlled by varying the feed rate from 0.5 to 1.5 ml h⁻¹. The synthesized NFs are studied for their morphological, optical, structural and compositional properties. The surface morphological analysis of the TiO₂ NFs revealed that the feed rate is playing a key role in order to control the diameter. The X-ray diffraction (XRD) analysis revealed that the formation of anatase TiO₂ with the tetragonal crystal structure. The compositional analysis showed the formation of pristine TiO₂ NFs. Further, the mp-TiO₂ and TiO₂ NFs paste were prepared and deposited on FTO substrate via doctor blade method and successfully used as a photoanode for indoline (DN350) dye DSSCs. Our optimized devices showed highest 3.92% PCE with J_SC of 9.73 mAcm⁻², V_OC of 0.650 V and FF of 0.62 for TiO₂ NFs prepared at 1.0 ml h⁻¹ feed rate.
