Adsorption and Sensitizing Properties of Azobenzenes Having Different Numbers of Silyl-Anchor Groups in Dye-Sensitized Solar Cells
The effects of the silyl-anchor group number on the adsorption and the sensitizing properties were examined in sensitizing dyes for dye-sensitized solar cells by using 4-alkoxysilyl and 2,4-dialkoxysilyl azobenzenes. The TiO2 electrode with the 2,4-disilyl dye exhibited higher durability to water and better photovoltaic performance than that with the 4-monosilyl dye, although the amount of 2,4-disilyl dye molecules adsorbed on the TiO2 electrode was slightly smaller than in the case of 4-monosilyl dye.
