Synthesis ofTiO(2)nanostructures by green approach as photoanodes for dye-sensitized solar cells
Clean and green energy being worlds priority today, here in this work TiO(2)nanostructures were prepared via green route using the fruit extracts derived from pineapple, orange, and grapes as reducing agents respectively. The anatase phase of the prepared TiO(2)nanostructures was confirmed through the X-ray diffraction pattern and the Raman analysis, respectively. Field emission scanning electron microscope (FESEM) images of the samples was found to exhibit nanorods like morphology. Further, the functional groups and the optical properties of the synthesized TiO(2)andMurraya koenigiifruit dye were confirmed using Fourier-transform infrared spectroscopy (FT-IR) and UV-Vis spectroscopy, respectively. From the Tauc plot, the indirect bandgap values of the TiO(2)nanostructures were calculated. Using the prepared TiO(2)nanostructures as photoanodes dye-sensitized solar cells were fabricated and its performance was studied. In this work, two different dyes such as the natural extract derived from the fruit skin ofMurraya koenigiiand the commercial N719 dye were used as sensitizers.
