Abstract

This paper investigates the enhancement of absorption in thin-film silicon solar cells using rectangular prism nanoparticles, analyzed through the finite-difference time-domain method. The study incorporates perfectly matched layer boundaries and periodic boundary conditions to accurately model light interaction. Monitors placed 5 nm within the silicon layer are used to assess input and output light intensities and minimize undesired reflections. The primary focus is on studying the impact of nanoparticle positioning within the silicon layer (referred to as buried nanoparticles) on absorption enhancement. Results indicate that absorption enhancement increases as nanoparticles are buried deeper into the silicon absorber layer, up to a depth of 60 nm. However, beyond this depth (up to 80 nm), the enhancement diminishes, achieving only 40% of the maximum enhancement observed. When nanoparticles are buried 100 nm into the silicon absorber layer, the absorption enhancement reaches 84%, representing the highest reported enhancement in this study.

利用埋银纳米粒子增强薄膜硅太阳能电池的吸收能力
本文通过有限差分时域法分析,研究了使用矩形棱镜纳米粒子增强薄膜硅太阳能电池吸收的问题。研究结合了完全匹配的层边界和周期性边界条件,以准确模拟光的相互作用。放置在硅层内 5 nm 处的监测器用于评估输入和输出光强度,并最大限度地减少不必要的反射。主要重点是研究硅层内纳米粒子定位(称为埋入纳米粒子)对吸收增强的影响。结果表明,随着纳米粒子埋入硅吸收层的深度增加,吸收增强效果也随之增加,最深可达 60 纳米。然而,超过这个深度(最多 80 纳米),增强效果就会减弱,仅为观察到的最大增强效果的 40%。当纳米粒子埋入硅吸收层 100 nm 时,吸收增强率达到 84%,是本研究中报告的最高增强率。
