Plasmonic nanostructures for organic photovoltaic cells — •Yagmur Ipek, Dominik A.Gollmer, Christopher Lorch, Frank Schreiber, Dieter P. Kern, and Monika Fleischer — Institute for Applied Physics, Eberhard Karls University of Tübingen, Auf der Morgenstelle 10, 72076 Tübingen, Germany

The topic of our research are OVP cells prepared by organic molecular beam deposition (OMBD). Diindenoperylen (DIP) [1] is used as the electron donor and Buckminster-Fullerene (C60) as the electron acceptor. The goal is to increase the efficiency of OPV cells by fabricating the transparent electrodes of OVP cells with plasmonic nanostructures, in particular gratings, such that the light harvesting properties of these cells may be improved. The plasmonic nanostructures are fabricated by electron-beam lithography or nanoimprint lithography. The OVP cells are measured via their current-voltage characteristics (I-V curve). Optical characterization of the structures by extinction measurements are compared with numerical simulations. An overview over the composition, different methods of nano fabrication and measurement methods of OVP cells will be presented.
