Strong localized surface plasmon resonance (LSPR) field, which is generated from gold nanoparticles, may enhance photons absorption of dyes in dye-sensitized solar cells (DSSCs), resulting in the improvement of their power conversion efficiency (PCE). In this paper, we report the incorporation of oleylamine capped gold nanoparticles (AuOA NPs) into the N-719 dye layer in DSSCs. The cells were prepared by varying the weight percentage of AuOA NPs with respect to the dye weight in dye solutions. The dye solutions containing 1.44[Formula: see text]wt.%, 1.92[Formula: see text]wt.% and 2.4[Formula: see text]wt.% of AuOA NPs exhibited an enhancement in their absorption spectra in the UV-Visible range, which may be the result of the excitation of localized SPR. The [Formula: see text] characteristics of those DSSCs show an enhancement in their photocurrent along with their PCE, from 4.18% to 5.14% for the cells made from the dye solutions without AuOA and with addition of 2.4[Formula: see text]wt.% of AuOA, respectively. This improvement is due to the enhancement of light absorption and hence charge carrier generation by the Plasmonic wave generated by AuOA NPs through the LSPR phenomenon.

通过金纳米粒子的局部表面等离子体共振效应提高染料敏化太阳能电池的效率

由金纳米粒子产生的强局域表面等离子体共振 (LSPR) 场可以增强染料敏化太阳能电池 (DSSC) 中染料的光子吸收,从而提高其功率转换效率 (PCE)。在本文中,我们报告了将油胺封端的金纳米粒子 (AuOA NPs) 掺入到 DSSC 中的 N-719 染料层中。通过改变 AuOA NPs 相对于染料溶液中染料重量的重量百分比来制备细胞。含有 1.44[公式:见正文]wt.%、1.92[公式:见正文]wt.% 和 2.4[公式:见正文]wt.% 的 AuOA NPs 的染料溶液在 UV-可见范围,这可能是局部 SPR 激发的结果。公式:见文本] 这些 DSSC 的特性显示其光电流与 PCE 一起增强,对于由不含 AuOA 和添加 2.4 [公式:见文本] wt.% AuOA 的染料溶液制成的细胞,其光电流从 4.18% 提高到 5.14% , 分别。这种改进是由于光吸收增强,因此由 AuOA NPs 通过 LSPR 现象产生的等离子体波产生电荷载流子。
