研究了金纳米粒子(Au-NP)诱导的表面等离子体对有机光伏器件(OPV)性能的影响。在阳极缓冲层中掺入Au纳米粒子后，这些OPV的功率转换效率得到了提高。Au纳米粒子的加入增加了激子的产生速率和解离几率，从而提高了短路电流密度和填充因子。我们将器件性能的改善归因于局域表面等离子体共振激发产生的电磁场的局部增强。(C)2009年美国物理研究所。[DOI：10.1063/1.3174914]
We have explored the effect of gold nanoparticle (Au NP)-induced surface plasmons on the performance of organic photovoltaic devices (OPVs). The power conversion efficiency of these OPVs was improved after blending the Au NPs into the anodic buffer layer. The addition of Au NPs increased the rate of exciton generation and the probability of exciton dissociation, thereby enhancing the short-circuit current density and the fill factor. We attribute the improvement in device performance to the local enhancement in the electromagnetic field originating from the excitation of the localized surface plasmon resonance.
