Artificial nanostructuring of thin conjugated polymer films — •Ali Özkü, Franziska Löhrer, and Peter Müller-Buschbaum — TU München, Physik-Department, LS Funktionelle Materialien, 85748 Garching, Germany

Conjugated polymer films have received great attention due to many applications in organic electronics, as for example organic solar cells. In particular, novel low band gap polymers have shown to give rise to high power conversion efficiencies. An artificial nanostructuring of the polymer films can add an additional benefit with regard to applications, as for example the photon management can be tailored. In the present work, we combine low band gap polymers with an artificial nanostructuring of the polymer film by soft embossing methods. The optical properties of nanostructured thin films are investigated with UV/Vis and photoluminescence measurements. Morphological studies include optical microscopy, AFM and X-ray diffraction methods. From a combination of these findings, we aim on establishing a structure-function relationship.
