Abstract
A theoretical explanation of optics behind TiO2has been presented with the help of a four phase model air/glass/ indium doped tin oxide/TiO2designed by modifying Rouard’s model to calculate the final transmittance in to TiO2layer. An optical simulation for the reflectance and transmittance has been executed for the synthesized nanocrystalline TiO2films. To validate the theoretical results TiO2film 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 TiO2layer, and that can be done only if one knows transmittance.
