In order to improve the solar cell efficiency of highly durable glass-substrate dye sensitized solar cll (DSC) using 3-methoxypropionitrile (MPN) electrolyte solvent, a systematic study on the optimization of TiO_2 photoelectrode was conducted. By the fine tuning of light harvesting efficiency (LHE) and film thickness of TiO_2 photoelectrode to the optimized structure, solar cell efficiency improved from 7.2% up to 8.5%. Moreover, the co-sensitization of black dye with organic dye, D131, was applied to MPN electrolyte system. Finally, efficiency improved up to 9.0%, which is one of the highest efficiencies in MPN-based DSC system.
