We fabricated a plasmonic layer by immobilizing both Au and Ag nanoparticles via P4VP on a photoactive layer for dye-sensitized solar cells (DSSCs) to prevent aggregation of metal nanoparticles, to increase absorbance of N719 dye, and to enhance light harvesting and power conversion efficiency (PCE). The optimal conditions for immobilizing these nanoparticles were also examined. With plasmonic Au and Ag nanoparticles, the PCE increased by 8.05% and 5.78%, respectively (plasmonic Au nanoparticles: from 8.82% to 9.53%; plasmonic Ag nanoparticles: from 8.82% to 9.33%). When both Au and Ag nanoparticles were employed in the plasmonic layer, the PCE showed further improvement of 10.17%, corresponding to a 15.31% enhancement. This significant improvement of the PCE could be explained by a broader range of light absorption resulting from the presence of the plasmonic layer.

含Ag和Au纳米粒子的等离激元单层薄膜的制备，用于染料敏化太阳能电池

我们通过在染料敏化太阳能电池（DSSC）的光敏层上通过P4VP固定Au和Ag纳米粒子来制造等离子体层，以防止金属纳米粒子聚集，增加N719染料的吸收率并增强光收集和功率转换效率（PCE）。还研究了固定这些纳米颗粒的最佳条件。使用等离子Au和Ag纳米粒子，PCE分别增加了8.05％和5.78％（等离子Au纳米粒子：从8.82％增加到9.53％；等离子Ag纳米粒子：从8.82％增加到9.33％）。当在等离子体层中使用Au和Ag纳米颗粒时，PCE表现出进一步的提高，达到了10.17％，相当于提高了15.31％。
