Plasmon-assisted energy conversion is investigated in a comparative study of dye-sensitized solar cells (DSCs) equipped with photo-anodes, which are fabricated by forming gold (Au) and silver (Ag) nanoparticles (NPs) on an fluorine-doped tin oxide (FTO) glass surface by means of dry plasma reduction (DPR) and coating TiO₂ paste onto the modified FTO glass through a screen printing method. As a result, the FTO/Ag-NPs/TiO₂ photo-anode showed an enhancement of its photocurrent, whereas the FTO/Au-NPs/TiO₂ photo-anode showed less photocurrent than even a standard photo-anode fabricated by simply coating TiO₂ paste onto the modified FTO glass through screen printing. This result stems from the small size and high areal number density of Au-NPs on FTO glass, which prevent the incident light from reaching the TiO₂ layer.
在一项对比研究中，对配备有光阳极的染料敏化太阳能电池（DSC）进行了等离子体辅助能量转换的研究。这些光阳极是通过干法等离子体还原（DPR）在氟掺杂氧化锡（FTO）玻璃表面形成金（Au）和银（Ag）纳米颗粒（NP），并通过丝网印刷法将TiO₂浆料涂覆在改性FTO玻璃上制备而成。结果，FTO/Ag-NPs/TiO₂光阳极的光电流增强，而FTO/Au-NPs/TiO₂光阳极的光电流甚至比通过简单地通过丝网印刷将TiO₂浆料涂覆在改性FTO玻璃上制备的标准光阳极还要少。这一结果源于FTO玻璃上Au-NP的尺寸小且面数密度高，这使得入射光无法到达TiO₂层。
