Design and Performance Analysis of Multilayer Coating of SnO2 Doped TiO2 Coated Photovoltaic Solar Cells
Abstract— This investigation deals with the synthesis of pure SnO2 doped TiO2 nanoparticles and fabrication of solar cell by hydrothermal method. The preparation of pure TiO2 involves mixing of Titanium Tetrachloride and Tin Chloride with double distilled water taken as first precursor solution and Ammonia solution was taken as one of the precursor solutions. The titanium precursors were added dropwise into the first precursor under vigorous stirring in room temperature with an equal interval of time. The photocatalytic activity of the SnO2-mixed TiO2 nanoparticles dramatically increased. The increased photocatalytic activity is mainly attributed to the improved charge separation of the TiO2 nanoparticles with the SnO2. The Obtained nanoparticles are coated in the solar cells and the solar cells are tested with several characterizations. After performing the post-synthesis treatments of SnO2 doped TiO2, the fine nanopowders are obtained. To assess the physical and chemical properties of the powders, they were characterized using FTIR, E-DAX, UV-VIS SEM analysis. The band gap of TiO2 nanoparticles was identified by UV-VIS spectral analysis. SEM analysis which revealed the morphology of the TiO2 nanoparticles E-DAX which confirms the purity of TiO2 nanoparticles. The Efficiency analysis is done on several layers of coated solar cells.
