摘要
表面等离子体激元共振是金属纳米结构非常独特的光学特性,对基于表面等离子体激元共振的纳米结构体系的研究已形成了一门新兴的学科,即表面等离子体光子学。可以利用金属纳米颗粒光散射、近场增强以及高度局域的表面等离子体极化激元增强薄膜太阳电池光吸收,提高电池转换效率。当前,表面等离子体光子学应用于太阳电池的设计已成为国际上光伏研究迅猛发展的一个热点。文章主要介绍表面等离子体激元增强薄膜太阳电池光吸收的原理及其在光伏器件中应用的最新研究进展。
Surface plasmons resonance is an unique optical property of metallic nanostructures.The recent extensive research on surface plasmons in metallic nanostructures has merged into a new subject,named plasmonics.By using light trapping through the resonant scattering and the near field enhancement in arrays of metal nanoparticles,or by coupling light into surface plasmon polaritons modes that propagate in the plane of the semiconductor layer,the enhancement of light absorption and the improvement of conversion efficiency in thin film solar cells are becoming possible.Currently,plasmonics for solar cell design has become an international research field of photovoltaic devices.In this paper,the principle of surface plasmons enhancement light absorption of thin film solar cells and the recent progress of applications in photovoltaic devices are reviewed.
