摘要:
设计了一种吸收层为双填充比矩形光栅结构的碲化镉薄膜太阳能电池,利用时域有限差分法对矩形光栅和双填充比矩形光栅碲化镉吸收层在250～1000nm入射波长范围内的吸收效率进行分析.实验结果表明:相比于平板型吸收层,单填充比和双填充比矩形光栅结构的吸收效率均有较大提高;双填充比矩形光栅在整个可见光范围内的吸收率整体得到提高,其对可见光的平均吸收率相比于平板型至少提高10％.可见通过优化太阳能电池吸收层的结构,光子在光栅内的随机反射增加了光在吸收层的作用时间和距离,提高了薄膜太阳能电池的光电转换效率.
Abstract:
A cadmium telluride thin film solar cell with a double filling ratio rectangular grating structure was designed. The cadmium telluride thin film solar cell with a rectangular grating and a double filling ratio rectangular grating in the incident wavelength range of 250-1000nm was analyzed using the finite-difference time domain method. The absorption efficiency is analyzed. The experimental results show that: compared with the flat absorbing layer, the absorption efficiency of the single filling ratio and double filling ratio rectangular grating structure is greatly improved; the absorption rate of the double filling ratio rectangular grating in the entire visible range is overall It is improved, and its average absorption rate of visible light is at least 10% higher than that of the flat plate type. It can be seen that by optimizing the structure of the solar cell absorption layer, the random reflection of photons in the grating increases the action time and distance of light in the absorption layer, improving The photoelectric conversion efficiency of thin film solar cells.
