通过在二氧化钛缓冲层中掺入金和/或银纳米颗粒(NPs)，研究了反转聚合物/富勒烯太阳电池中的局域表面等离子体共振(LSPR)效应。通过金属纳米粒子的等离子体激元共振增强了对光的捕获。它改善了短路电流密度(JSC)，同时保持了相应的开路电压(VOC)。在二氧化钛中引入30%的银纳米粒子时，最大功率转换效率达到7.52%，与不含金属纳米粒子的参比器件相比，提高了20.7%。为了探索Au和/或Ag纳米粒子的等离子体效应对OSC性能的影响，系统地研究了金属Np掺杂的TiO2层的器件光伏特性、光电流特性、有源层的稳态和动态光致发光以及金属Np掺杂的TiO2层中的电场分布。
This paper investigates the effects of localized surface plasmon resonance (LSPR) in an inverted polymer/fullerene solar cell by incorporating Au and/or Ag nanoparticles (NPs) into the TiO2 buffer layer. Enhanced light harvesting via plasmonic resonance of metal NPs has been observed. It results in improved short-circuit current density (Jsc) while the corresponding open-circuit voltage (Voc) is maintained. A maximum power conversion efficiency of 7.52% is obtained in the case of introducing 30% Ag NPs into the TiO2, corresponding to a 20.7% enhancement compared with the reference device without the metal NPs. The device photovoltaic characteristics, photocurrent properties, steady-state and dynamic photoluminescences of active layer on metal NP-doped TiO2, and electric field profile in metal NP-doped TiO2 layers are systematically investigated to explore how the plasmonic effects of Au and/or Ag NPs influence the OSC performance.
