In this project, titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles were deposited on the Glass based flexible substrate. TiO2 and ZnO nanostructures were synthesized separately by using sol-gel method. Spin coater was used to prepare the TiO2/ZnO thin films on glass substrates. The surface morphology of TiO2 and ZnO was studied using a scanning electron microscope (SEM). The crystallinity and structure of the produced TiO2 and ZnO nanoparticles were investigated using X-ray diffraction (X-Rays). The optical absorption was measured using a UV-Vis spectrophotometer. Dye-sensitized solar cells (DSSCs) were proposed for the ZnO/TiO2/Glass films as the working electrode.enDepartment of PhysicsSP20PhysicsSolar Cell ApplicationsThin FilmsOptical PropertiesDr. Shahzada Qamar HussainThesis
