Abstract
In this paper we present the results of the numerical simulation using wx-AMPS1D software of a solar cell based on hydrogenated amorphous silicon (a-Si: H / c-SiGe), the top layer has the largest band gap, while the bottom layer has the smallest bandgap. This design allows less energetic photons to pass through the upper layer(s) and be absorbed by the layer below, which increases the overall efficiency of the solar cell to obtain an efficiency high conversion rate. As the results, remarkable improvements on Voc, Jsc and FF have been achieved with the incorporation of n-c-SiGe layer, we achieved an efficiency of 11.93%.
本文利用wx-AMPS1D软件对氢化非晶硅(a- si: H / c-SiGe)太阳能电池进行了数值模拟,结果表明,顶层的带隙最大,底层的带隙最小。这种设计允许较少能量的光子通过上层并被下层吸收,从而提高了太阳能电池的整体效率,从而获得高效率的高转换率。结果表明,n-c-SiGe层的加入对Voc、Jsc和FF都有显著的改善,效率达到11.93%。
