Abstract
The sol-gel spin coating method has been explored to prepare TiO/sub 2/ thin films for dye-sensitized TiO/sub 2/ solar cell application. Sol concentrated at 40/spl deg/C with 40% polyethylene glycol (PEG) by weight of TiO/sub 2/ added to the sol is found to give smooth, crack free and highly porous film with high cell efficiency. Thickness dependent optical absorption and cell performance are studied. Though light absorption gradually increases with film thickness, a saturation in short-circuit current occurs at higher thicknesses. Efforts are also made to improve the cell performance by modifying the electrolyte solvent and adding 4-tert butylpyridine.
