Effect of the Introduction of a CF₃ Group to a Silyl-Anchor Azobenzene Dye on Sensitization Property in Dye-Sensitized Solar Cells

Abstract:

The effect of the introduction of a CF₃ group to a silyl-anchor moiety of the sensitizer on the sensitizing property for the dye-sensitized solar cell was examined by using alkoxysilyl-anchor azobenzene dyes. The cell sensitized by the silyl-anchor dye with the electron-withdrawing CF₃ group in the silyl-anchor moiety exhibited higher photovoltaic performance than that by the silyl-anchor dye without the CF₃ group.
