用于增强透明有机太阳能电池中的光捕获的纳米天线
Nanoantennas for enhanced light trapping in transparent organic solar cells
摘要:
我们提出了一种陷光结构,它能显著增强有机太阳能电池在红外波段的光伏吸收,同时保持足够高的可见光透射率。光捕获的主要机制与金属纳米天线阵列的集体振荡的激发有关,其特征在于太阳能电池的体积中的有利场分布。它允许红外光伏吸收增加三倍以上。
英文摘要:
We propose a light-trapping structure offering a significant enhancement of photovoltaic absorption in transparent organic solar cells operating at infrared while the visible light transmission keeps sufficiently high. The main mechanism of light trapping is related with the excitation of collective oscillations of the metal nanoantenna arrays, characterized by advantageous field distribution in the volume of the solar cell. It allows more than triple increase of infrared photovoltaic absorption.
