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.
