TiO2: rGO doped material is deposited on glass and Si substrates. These hetero nanostructures have multiple applications in photovoltaic because of their charge transport properties. In this study, we prepared tetragonal TiO2: rGO doped material is deposited on glass and Si substrates (NCs) using Thermal Evaporation method. The morphological properties of the NCs were investigated using X-ray diffraction, Field-emission scanning electron microscopy with EDAX analysis, Atomic force microscopy, and Photovoltaic studies analysis. The results showed that the surface area of the deposited films increased significantly and the anatase TiO2: rGO doped material is deposited on glass and Si substrates was efficient photovoltaic performance with the other nanocomposites or the bare individual nanoparticles. It may be attributed to the increased active surface area, the increased adsorption of the light andtarget surface atoms, as well as efficient electron–hole transformation.
