摘要
利用传递矩阵法(TMM)优化设计多种介质膜材料的单层、双层增透膜结构。利用Silvaco 软件的ATLAS 器件仿真模块建立基于优化增透膜结构的二维晶硅太阳电池结构。对比分析了具有不同单层、双层增透膜结构的晶硅太阳电池的光谱响应情况。结果表明:在200~1100 nm 波长范围内,由多种不同介质材料组成的双层增透膜比单层增透膜具有更小的光反射损耗;双层增透膜结构可有效降低晶硅太阳电池的光谱响应损耗,且性能优于单层增透膜情况。其中MgF2/ZnS 双层增透膜减反效果最好,对380~1000 nm 波长范围的入射光,可将上表面光反射率降低到5%以下。
Abstract
Single- and double-layer anti-reflection coatings with many kinds of common dielectric coat materials are designed and optimized based on the transfer matrix method (TMM). A two-dimensional crystal line silicon solarcell structure model based on different anti-reflect coatings is established using Silvaco ATLAS device simulation software. The effect of light absorption is analyzed and evaluated by comparing the spectral responses of cells with different single and double-layer anti-reflection coatings. The results show that the crystalline silicon solar cell with double- layer anti- reflection coatings has more effective absorption spectrum when the wavelength range is from 200 nm to 1100 nm. Compared with single- layer anti- reflection coatings, the double layers composed of different dielectric materials have smaller light reflection loss, the double-layer coatings can reduce the loss of the spectral response effectively, and its performance is better than single-layer coatings. MgF2/ZnS double-layer coatings have the best anti-reflection effect and the light reflectance can be reduced to lower than 5% for the incident light with wavelengths of 380~1000 nm.
