Diferuloylmethane anchored anatase TiO2 nanoparticle for dye sensitized solar cell

Abstract

Dye sensitized solar cells (DSSC) have been constructed by using diferuloylmethane dye as natural photosensitizers for anatase nanostructure TiO₂ thin film coated on FTO conductive glass substrate. Structural and morphological properties of the semiconductor films have been characterized by X-ray diffractometer and scanning electron microscopy, respectively, as well as, the wavelength of the maximum absorbance of the dye anchored on TiO₂ film has been studied by using UV-Vis spectrophotometer. The XRD pattern of TiO₂ thin films made by Doctor-blading deposition technique has revealed that the grain size of TiO₂ is equal to 40 nm. The photovoltaic performance of the cells have been investigated in terms of power conversion efficiency, furthermore the effect of different spectroscopic parameters on the PV performance of constructed DSSC has been studied.
