Fabrication of Dye sensitized solar cell by spherical and Nano pore TiO2 structure

The present work studies new proposed formation of Titanium Dioxide for fabricating Dye sensitized solar cells، (DSSCs). Titanium Dioxide was synthesized by hydrothermal method. Deposition of the layers performed with electrophoretic method. In addition، materials used to synthesis are inexpensive. Two structures have been synthesized in different spheres of nanometer dimensions with diameter in rang 400-500 nm and the other with nano pore in rang 20-50 nm. The efficiencies of these Cells are reliable and repeatable. Morphologies and crystal structures were studied by Scanning electron microscopy and XRD pattern respectively. The obtained power conversion efficiencies for DSSCs sensitized with these processes were 3. 8 and 6. 1 percent respectively. shear stresses in TGO layer were also calculated and the results show these stresses are 35% lower than micro ones. Modeling results validates long life time of nano-structured coatings.
