金属纳米粒子对非晶硅太阳能电池性能影响的理论模拟
DOI: 10.3969/j.issn.1671-7627.2015.04.019, PP. 109-113
Keywords: 非晶硅太阳能电池,有限时域差分,光吸收增强
Abstract:
使用时域有限差分(fdtd)方法,在标准太阳光下模拟非晶硅太阳能电池表面上有序排列的ag或au纳米颗粒对电池的光吸收增强效应。结果表明:通过改变金属颗粒的直径和粒子周期性间距等不同条件,光吸收的增强效应有规律地变化。结合amps-1d模拟软件对非晶硅电池的电学性能进行计算,在标准太阳光下,使用直径为200nm、周期性间距为600nm的ag纳米粒子可以使非晶硅电池效率的提高幅度达到23.4%。
