Abstract In this study, we demonstrate the fabrication of hybrid plasmonic solar cells using gold nanoparticles (AuNPs). Two types of AuNPs, gold nanospheres (AuNSs) and gold nanorods (AuNRs), were incorporated in a hole transport layer (HTL) (PEDOT:PSS) on a metallic grating electrode. The organic solar cells (OSCs) structure comprised an indium-tin-oxide (ITO)-coated glass substrate/PEDOT:PSS:AuNSs:AuNRs/P3HT:PCBM/Al grating electrode. Adding AuNPs induced localized surface plasmon resonance (LSPR), while grating structured Al at the interface with a photoactive layer excited the propagating surface plasmons. Compared with a flat reference device, the proposed OSCs exhibited improved photovoltaic properties by increasing both the short-circuit current density (JSC) and the power conversion efficiency (PCE) with large enhancements of 16.23% and 14.06%, respectively. The efficiency improvement was attributed to increased broadband absorption and improved electrical properties inside the thin-film devices.

通过在金属光栅表面加入混合金纳米球和金纳米棒来增强有机薄膜太阳能电池

摘要 在这项研究中，我们展示了使用金纳米粒子 (AuNPs) 制造混合等离子体太阳能电池。两种类型的 AuNP，金纳米球 (AuNSs) 和金纳米棒 (AuNRs)，被结合在金属光栅电极上的空穴传输层 (HTL) (PEDOT:PSS) 中。有机太阳能电池 (OSC) 结构包括氧化铟锡 (ITO) 涂层玻璃基板/PEDOT:PSS:AuNSs:AuNRs/P3HT:PCBM/Al 光栅电极。添加 AuNPs 诱导局部表面等离子体共振 (LSPR)，同时在具有光敏层的界面处光栅结构化 Al 激发传播的表面等离子体。与平面参考器件相比，所提出的 OSC 通过增加短路电流密度 (JSC) 和功率转换效率 (PCE) 来表现出改善的光伏性能，并大幅提高了 16。分别为 23% 和 14.06%。效率的提高归因于薄膜器件内部宽带吸收的增加和电性能的改善。
