Development of dye sensitized solar cells using local electric field reinforcement with surface control metal nano particle

用聚丙烯酸酯基梳状嵌段共聚物修饰银纳米粒子表面等离子体，提高了染料敏化太阳能电池（DSSC）的光电转换效率。将聚合物修饰的银纳米颗粒插入DSSC中TiO2薄膜的孔中。在此基础上，研究了银纳米粒子光吸收增强DSSC （PE-DSSC）的性能。为了明确Ag纳米粒子对DSSC特性的影响，DSSC中TiO2膜的厚度为2mm，比典型的DSSC （10mm）薄。与不含银纳米颗粒的DSSC相比，PE-DSSC的Eff提高了2.5%。

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.
