The proposed work suggests the fabrication of hybrid TiO₂/reduced graphene oxide composites with self-assembled multidimensional structure. The two step facile alkaline hydrothermal route is implemented using variable wt% of GO for the successful synthesis of multidimensional reduced graphene oxide TiO₂ composites structure (MGTS). In the first step, TiO₂ aggregates (TNA) were prepared by low temperature hydrothermal process. Subsequently, growth of multidimensional TiO₂ on hGO sheet, as well as simultaneous reduction of GO is done and the as prepared MGTS is applied for dye sensitized solar cell (DSSC). Structural and surface morphology of the developed samples were investigated by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) techniques. The X-ray photoelectron spectroscopy studies monitored the chemical composition and surface binding energy of TNA and MGTS samples. The current-voltage (J-V) and electrochemical impedance studies evaluates the performance of the TNA and MGTSs photoanodes in DSSC. The finest loading of GO in the TiO₂ matrix assisted the accelerated electron transport channel within the TiO₂ matrix resulting in superior photo conversion efficiency of 8.62% as compared with neat TiO₂ which has an efficiency of 6.3%.
