本文描述了一种改善聚合物体异质结太阳电池性能的协同等离子体效应。在阳极缓冲层中掺入银和金纳米粒子后，双纳米粒子在增强光吸收方面表现出比单一纳米粒子更好的行为，从而实现了功率转换效率为8.67%的聚合物太阳能电池，提高了20%。协同等离子体效应是由两种不同的纳米粒子的双重共振增强引起的。通过比较金纳米棒和金纳米颗粒在太阳能电池中的应用，这一想法进一步被揭穿。详细的研究揭示了等离子体纳米结构对激子产生、解离、电荷复合和薄膜器件内输运的影响。
This article describes a cooperative plasmonic effect on improving the performance of polymer bulk heterojunction solar cells. When mixed Ag and Au nanoparticles are incorporated into the anode buffer layer, dual nanoparticles show superior behavior on enhancing light absorption in comparison with single nanoparticles, which led to the realization of a polymer solar cell with a power conversion efficiency of 8.67%, accounting for a 20% enhancement. The cooperative plasmonic effect aroused from dual resonance enhancement of two different nanoparticles. The idea was further unraveled by comparing Au nanorods with Au nanoparticles for solar cell application. Detailed studies shed light into the influence of plasmonic nanostructures on exciton generation, dissociation, and charge recombination and transport inside thin film devices.
