| Research Abstract |
Photoelectric conversion efficiency (Eff) of a dye-sensitized solar cell (DSSC) was improved by localized surface plasmon on silver (Ag) nanoparticles modified with polyacrylate-based comb-shaped block copolymer. The polymer-modified Ag nanoparticles were inserted into pores of a TiO2 film in a DSSC. Then, the characteristics of this photoabsorption enhanced DSSC (PE-DSSC) with the Ag nanoparticles were evaluated. To clarify the effect of Ag nanoparticles on the characteristics, the thickness of the TiO2 film in the DSSC was 2mm, thinner than that for a typical DSSC (10mm). A PE-DSSC showed an improved Eff of 2.5%, compared with about 1.5% for a DSSC with no Ag nanoparticles.
