摘要

采用传输矩阵法的光学模型以及MATLAB软件模拟了硅基有机太阳能电池对入射光的吸收率和各层厚度的关系。模拟表明活性层对入射光的吸收率主要受其自身厚度影响

且由于微腔效应

这种结构的电池可以很大程度上优化活性层厚度;另外通过调节折射率匹配层厚度和传输层厚度也可以优化活性层对入射光的吸收率。在本文所讨论的厚度中

最佳传输层厚度为10 nm左右

最佳匹配层厚度为30 nm ZnS或者60 nm Alq

。

Abstract

The effects of active layer thickness

capping layer thickness and transport layer thickness on the optical absorption of active layer have been investigated by employing MATLAB and an optical model based on the transfer matrix method. The results reveal that the absorption of active layer is mainly attributed to its thickness which could be optimized by the microcavity effect. Furthermore

it demonstrates that active layer optical absorption can be effectively improved by adjusting the thickness of capping layer and transport layer. At last

the results show that the solar cells with 10 nm thick transport layer have superior optical and electrical performance than those without transport layer; the optimized thickness of ZnS layer and the thickness of Alq

layer are 30 nm and 60 nm

respectively. The research of optical properties of organic solar cell on Si substrate provides a theoretical basis to its future structural design and application.
