Abstract
We attempted to manufacture nano-scale structures which were applied in the organic solar cell in this thesis, and further we used the simulation to discuss the functions of the metallic nanostructures as surface plasmon polariton (SPP) effect and the light scattering effect. It was anticipated to utilize the enhancement of power conversion efficiency in organic solar cell.n the theoretical part, we used finite difference time domain (FDTD) to calculate the electromagnetic fields and data analysis by using MATLAB or Sigmaplot, and then confirmed the influence of the organic solar cell efficiency by metallic nanostructures. For example, we discussed different parameter as metal materials, sizes, shapes, periods to probe into transmission and localized intensity in active layer of organic solar cell. Further we designed several kinds of organic solar cell device to confirm whether it is feasible to increase power conversion efficiency or not.n the experimental part, we mainly fabricated three kinds of polymer solar cell device. The first kind is that incorporating gold nanoparticles which generated by chemical synthesis to the organic solar cell. The second, third kind of the device thatusing e-beam lithography to manufacture different shapes of nanostructure as circle, triangle and square arrays and different periodic gold grating on ITO electrode. And we measured I-V curve and IPCE to prove efficiency enhancement of organic solar cell. Besides, we tried to fabricate active layer of polymer solar cells with periodic nanostructures by nanoimprint and etching.inally, we brought up a new organic solar cell with double nanostructures. It was expected to dominate incident light distribution of active layer via metallic nanostructure which matched main light-absorption polymer material. It will enhance light absorption heavily in active layer resulting in power conversion efficiency reach optimum value.
