Dye-sensitized Solar Cells Based on Silicon Dioxide Nanoparticles Photochemically Synthesized: A Comparative Study in the Concentration of the Dye-sensitized

Green energy is often derived from renewable energy technologies such as solar, wind, geothermal, biomass, and hydroelectric power as a source of energy. Every one of those technologies generates energy differently, whether it’s by harnessing the sun’s energy through solar panels, wind turbines, or the flow of water. In recent years, nanomaterials have been used in solar cells due to their high efficiency. Our study reported a new method (photolysis) to fabricate silicon dioxide (SiO2) nanoparticles. Various techniques investigated the synthesized sample. A transmitted electron microscope (TEM) was used to determine the particle size of nano-SiO2 and was found to be 20.7 nm. The amorphous structure of SiO2 nanoparticles synthesized was diagnoses via x-ray diffraction (XRD). The energy band gap is estimated to be 3.61 eV in Uv-visible spectroscopy to evaluate the nano-sample’s optical properties. Eventually, SiO2 nanoparticles were applied as a photoanode to assembled dye-sensitized solar cells (DSSC). Photo-current short-circuits, photovoltaic open-circuit, and DSSC power conversion output was evaluated using an I – V measurement system. The effects of the concentration of Rhodamine 6G dye-sensitized on DSSC power conversion performance have also been studied. The cell power conversion efficiency with increased dye concentrations was mainly increased, with maximum efficiency of 2% at 20 mm of dye concentration. Finally, it can be reported that silicon oxide nanoparticles can be used as anode electrodes in dye-sensitized solar cells, as they are highly effective.
