Abstract: A theoretical and experimental study of plasmonic organic solar cells with the metallic nanostructures is presented in this talk. From theoretical study, the physics of the performance enhancement of the organic solar cell is explained by multiphysics model of plasmonic organic solar cells. Meanwhile, we have also experimental investigated the plasmo-optical and plasmo-electrical effects with various metallic nanostructures such as metallic nanoparticles and metallic nanogratings into different regions of the solar cells. We will also introduce novel low-temperature solution-based approaches to fabricate novel carrier transport layers and electrode for the emerging technologies of low-cost and large area photovoltaics.

Our results show that the power conversion efficiency of organic solar cells can be enhanced by over 30% and the value of power conversion efficiency can reach about 9% depending on the metallic nanostructures, device structures, and the polymer materials. Details of the improvement will be discussed.
