展示了一种用于等离子体太阳能电池的金属纳米颗粒涂层的合成方法，该方法可以满足大规模工业需求。利用紫外脉冲激光在聚合物材料表面制备Au和Ag纳米粒子，以提高等离子体有机光伏器件的性能。证明了对颗粒尺寸和密度的控制。使用实验和计算机模拟严格检查这些嵌入的粒子的功率转换效率的光学和电学效应。特定尺寸和空间分布的金纳米颗粒提高了器件效率。基于我们的研究结果，我们提出了设计考虑，利用整个AM1.5光谱使用等离子体结构，提高效率的聚合物太阳能电池，使用广谱等离子体。
A method for the synthesis of metal nanoparticle coatings for plasmonic solar cells which can meet large scale industrial demands is demonstrated. A UV pulsed laser is utilized to fabricate Au and Ag nanoparticles on the surface of polymer materials which form the substrates for plasmonic organic photovoltaic devices to enhance their performance. Control of the particles' size and density is demonstrated. The optical and electrical effects of these embedded particles on the power conversion efficiency are examined rigorously using both experimental and computer simulation. Gold nanoparticles of particular size and spatial distribution enhance the device efficiency. Based on our findings, we propose design considerations for utilizing the entire AM1.5 spectrum using plasmonic structures towards enhancing the efficiency of polymer solar cells using broad spectrum plasmonics.
