Outline of Final Research Achievements

Dye-sensitized solar cell is known as a low-cost solar cell. The efficiency of the DSC is strongly influenced by the surface condition of the TiO2 nano structure in the cell. We investigated effect of the chemical- and physical-treatments of the TiO2 surfaces to the solar cell performance. First finding is that chemical treatment by the ammonium pyrrolidinedithiocarbamete (APDTC) increases the amount of the N719 dye on the TiO2 surface. We found that the oxidized sulfur enhances the surface positive charge on the Ti atom. and thus, short circuit current is increased by the APDTC treatment. Next, we found the open circuit voltage of TiO2 nanotube type DSC is increased by Zn atom attachment at the surface.
