摘要

We have designed a high efficiency organic solar cell with light trapping structure on transference cylindrical substrate. An electrical and optical simulation of the light trapping structure has been performed on the basis of finite element and transfer matrix formalism methods. Absorption spectrum, internal quantum efficiency, external quantum efficiency, maximum power output and efficiency of the organic solar cell are simulated and presented in terms of three variables: the height, diameter of the glass substrate and the thickness of the organic active layer. The efficiency of the proposed organic solar cell with light trapping structure is enhanced by a factor of 2 than the similar structure on the flat plain glass substrate. The optimum organic active layer thickness to achieve the highest efficiency is shifted from 65 to 20 nm. Finally, we have investigated the effect of light incident angle on the performance of the proposed cell structure.
