In this work, we describe the efficiency enhancement in dye-sensitized solar cells (DSSCs) by using TiO/silver nanoplate plasmonic nanocomposite photoanodes. The nanocomposite photoanodes with tunable plasmonic properties assembled from shape/size-selected silver (Ag) nanoplates were applied to enhance the light absorption for high-performance DSSCs. It was found that the localized surface plasmon resonance can be tuned over a range from 500 to 1000 nm, which is strongly dependent on the shape and size of Ag nanoplates and the refractive index of the surrounding dielectric. The effects of the size and shape of Ag nanoplates on the surface plasmonic resonance and the efficiency of DSSCs were evaluated experimentally. Furthermore, a three-dimensional finite element method was employed to investigate the localized surface plasmon resonance (LSPR) for the shape and size effect of Ag nanoplates.
在这项工作中，我们描述了通过使用 TiO/银纳米板等离子体纳 米复合光阳极来提高染料敏化太阳能电池 (DSSC) 的效率。由形状/尺寸选择的银 (Ag) 纳米板组装而成的具有可调等离子体特性的纳 米复合光阳极被应用于提高高性能 DSSC 的光吸收。发现局域表面等离 子体共振 (LSPR) 可以在 500 到 1000nm 的范围内进行调节，这强烈依赖于 Ag 纳米板的形状和尺寸以及周围介电质的折射率。实验评估了 Ag 纳米板的尺寸和形状对表面等离子体共振和 DSSC 效率的影响。此外，还采用三维有限元方法研究了 Ag 纳米板的形状和尺寸效应对局域表面等离 子体共振 (LSPR) 的影响。
