摘要
针对有机给体-受体型异质结薄膜太阳电池,基于薄膜中的光学干涉效应和激子扩散理论建立模型,定量分析了有机层厚度对太阳电池性能的影响,通过限制有机光敏层厚度来控制由光学干涉效应引起的局部光子密度(光强度)的分布,进而优化有机层的吸收效率和激子扩散效率,以此达到提高器件光伏效率的目的.并通过实验进行了验证.
With the optical interference and exciton diffusion principle, the mechanism and process in a typical organic donor-acceptor solar cell are analyzed and simulated in virtue of a model established by MATLAB software. The effect of the organic film' s thickness on the characteristics of organic solar cell is analyzed quantitatively, photo-absorptivity and exciton diffusivity are optimized by confining the thickness of organic active layers. The reliability of optimized model is validated by experiment.
