    Investigations on Silicon Dioxide Nanostructures for the Applications of TOPCON Solar Cells
    (2022) Sidra Abdullah; CIIT/FA20-RPH-012/LHR; Dr. Shahzada Qamar Hussain; LHR TP 7974
    Silicon has been considered the best material for the fabrication of solar cells due to its non- toxicity, abundance, high and stable cell efficiencies, and industrial technological approaches. In this project, silicon dioxide (SiO2) based nanostructures were synthesized using a solution- based sol-gel technique. Spin coater was used to deposit the thin films of SiO2 on a glass substrate. The surface morphology of SiO2 nanostructures was measured by using a scanning electron microscope (SEM). The structural analysis of SiO2 nanostructures was studied via X- ray diffraction (XRD) analysis. UV-Vis spectrophotometers were used to measure the optical properties of SiO2 thin films. The simulation was used to study the influence of SiO2 and other layers on the TOPCON solar cells

    Fabrication and Characterization of TiO2/ZnO based Flexible Composite Films for Dye-Sensitized Solar Cells
    (2021) Ayesha Yasin; CIIT/SP19-RPH-036/LHR; Dr. Shahzada Qamar Hussain; LHR TP 7252
    Dye-sensitized solar cells (DSSCs) are considered as cost-effective photovoltaic devices due to their simple fabrication techniques. In this project, titanium dioxide (TiO2) and zinc oxide (ZnO) nanoparticles were deposited on the Lignocelluloses (LC) fiber based flexible substrate. To begin, TiO2 nanoparticles were synthesized using the sol-gel method, whereas ZnO nanoparticles were synthesized using the microwave assisted approach. The scanning electron microscope (SEM) was used to examine the surface morphology of TiO2 and ZnO, while the atomic force microscope was used to examine the 3D profile and roughness (AFM). X-ray diffraction (X-Rays) analysis was used to examine the crystallinity and structure analysis of produced TiO2 and ZnO nanoparticles. A UV-Vis spectrophotometer was used to measure optical absorption. Dye-sensitized solar cells were fabricated on the deposited ZnO/TiO2/LC (the working electrode)
