Abstract
The present research was carried out in understanding the enhanced efficiency of the I-V (current-voltage) properties of the novel inorganic nanocomposites (NCs) of Gd-TiO3. Nanocomposites of Gd-TiO3 synthesized by precipitation technique incorporating CTAB (cetyl trimethyl ammonium bromide) as capping agent characterized by XRD (X-ray diffraction), UV Visible, CV (cyclic voltammetry) SEM (scanning electron microscopy) analytical techniques. Tetragonal close packing of Gd-TiO3 NPs observed in XRD with particle overlay of Gd is 40 nm. Current-voltage properties studied with different concentration of Gd (10–40%) doped NS. The FF (fill factor) increases as the doping of Gd increases which indicates the increased charge dislocation inside the NCs of Gd-TiO3. The open circuit current (Voc) and power maximum also increases as the gadolinium concentration increases. The effect of the loading of the Gd on the conductivity of the NCs was investigated. The filler loading up to 30% I-V characteristics was linear and the 40% it shows non linearity in the I-V characteristics which shows the ohmic nature of the NCs and the electrodes. Impedance value decreases with increase in applied voltage. Current-voltage behavior of NCs depends largely on the Gd content and 40% filler loaded TiO3 showed better efficiency than the rest other NCs.
