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

利用聚丙烯酸酯梳状嵌段共聚物修饰的银纳米粒子的局域表面等离子体增强染料敏化太阳能电池的光电转换效率。将聚合物修饰的Ag纳米粒子插入到DSSC中的TiO 2膜的孔中。然后，这种光吸收增强DSSC（PE-DSSC）与银纳米粒子的特性进行了评价。为了阐明Ag纳米颗粒对特性的影响，DSSC中的TiO 2膜的厚度为2 mm，比典型DSSC的厚度（10 mm）薄。与没有Ag纳米颗粒的DSSC的约1.5%相比，PE-DSSC显示出2.5%的改进的Eff。

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.
