摘要

本文利用光学传递矩阵理论和Onsager-Braun公式，研究了SWCNTs含量对P3HT:PC60BM基BHJ OSC光学性能和EHP生成速率的影响。光学模拟结果表明，P3HT:PC60BM基BHJ OSC活性层复合材料中SWCNTs的存在通过拓宽近红外区吸收光谱提高了激子的产生速率。激子的产生速率和吸收强度随着swcnts添加量的增加而提高。此外，当swcnts添加量为1%时，活性层厚度相关的激子解离概率和EHP生成率最佳。

Improvement in the exciton and EHP generation rate of P3HT:PC60BM based BHJ OSCs with the incorporation of SWCNTs

In this paper the impact of SWCNTs content on the optical performance and EHP generation rate of P3HT:PC60BM based BHJ OSC is presented using the Optical transfer matrix theory and Onsager-Braun formulism. The results from our optical simulation show that the presence of SWCNTs in the active layer composite of P3HT:PC60BM based BHJ OSC improves the exciton generation rate by broadening the absorption spectra towards the NIR region. The exciton generation rate and intensity of absorption was seen to improve as the added content of SWCNT increased. Furthermore the active layer thickness dependent exciton dissociation probability and EHP generation rate was found to be optimal when the added content of SWCNT was at 1%.
