Abstract

An effective performance enhancement model for the thin film solar cell conjointly based on extraordinary transmission and nanoantenna is proposed and investigated. The absorber layer of the extraordinary transmission based solar cell contains a metallic thin film with periodic holes. Maximum extraordinary transmission is accomplished as the metallic film has the same refractive index on both sides. Increased light transmission causes the absorber layer to absorb more light, which increases short circuit current density and subsequently the efficiency of the thin film solar cell. The presented analysis demonstrates that adding a square nano patch on the top surface of the absorber layer can further boost the extraordinary transmission. The extraordinary transmission is increased because of the formation of cavity nanoantenna. Cavity nanoantenna increases the coupling of light into the hole due to the excitation of surface plasmons polaritons. The proposed design of solar cell exhibits around 98% absorption and the short circuit current density is increased by a factor of 3.23. The study has been carried out using finite difference time domain (FDTD) method.

基于超常传输和金属贴片纳米天线的智能城市兼容薄膜太阳能电池

本文提出并研究了一种基于非凡透射和纳米天线的薄膜太阳能电池的有效性能增强模型。基于超常传输的太阳能电池的吸收层包含一层带有周期性小孔的金属薄膜。由于金属薄膜的两面具有相同的折射率，因此可以实现最大的超常透过率。透光率的增加会使吸收层吸收更多的光，从而提高短路电流密度，进而提高薄膜太阳能电池的效率。分析表明，在吸收层顶面添加方形纳米贴片可进一步提高超常透过率。由于形成了空腔纳米天线，超常传输率得以提高。空腔纳米天线由于激发了表面等离子体极化子而增加了光与孔的耦合。拟议设计的太阳能电池的吸收率约为 98%，短路电流密度增加了 3.23 倍。研究采用有限差分时域（FDTD）方法进行。
