Canvas of Optics behind Nanocrystalline TiO₂ Film Engaged in Dye-Sensitized Solar Cells

Abstract:

A theoretical explanation of optics behind TiO₂ has been presented with the help of a four phase model air/glass/ indium doped tin oxide/TiO₂ designed by modifying Rouard’s model to calculate the final transmittance in to TiO₂ layer. An optical simulation for the reflectance and transmittance has been executed for the synthesized nanocrystalline TiO₂ films. To validate the theoretical results TiO₂ film has been deposited onto indium doped tin oxide (ITO) layer by sol-gel dip coating technique. The novelty of the task lies behind the fact that transmittance helps to calculate the light harvesting efficiency of the Dye-Sensitized solar cells which is the ratio of light actually harvested to the light actually reached to TiO₂ layer, and that can be done only if one knows transmittance.
