Abstract

We design and simulate a simple plasmonic absorber by employing a three-layer structure comprised of square nanoring array on top of the dielectric subtract followed by a gold reflector. To achieve near perfect absorption, several configurations of the top layer (plasmonic nanoparticle) are proposed, which includes a gold nanoring, horizontally split ring, vertically split ring and quad-split ring, respectively. Simulation results indicate that for some geometries, dual broad absorption bands with absorption efficiencies greater than 99% are obtained, which is highly suitable for solar cell applications.
用于太阳能电池的等离子体吸收体
我们设计并模拟了一个简单的等离子体吸收体,该吸收体采用三层结构,由介电减法上的方形纳米环阵列和金反射器组成。为了实现近乎完美的吸收,提出了几种顶层(等离子体纳米粒子)的结构,分别包括金纳米环、水平分裂环、垂直分裂环和四分裂环。仿真结果表明,对于某些几何形状,可以获得吸收效率大于99%的双宽吸收带,非常适合太阳能电池的应用。
