Design and fabrication of organic solar cells structured via nanoimprint lithography

A theoretical analysis based on a drift-diffusion simulation method is performed for investigating device performances of nanostructured organic solar cells. The results show an increase of the short-circuit current density, which can be attributed to the increased interface area. Patterning via nanoimprint techniques is demonstrated, which constitutes the first step towards the realization of bulk-heterojunction organic solar cells with controlled morphology.
