Investigation of novel material systems for increasing the efficiency of organic solar cells — •Christian Weindl, Franziska C. Löhrer, and Peter Müller-Buschbaum — TU München, Physik Department, LS Funktionelle Materialien, 85748 Garching

In the last decade, interest in organic photovoltaics has increased strongly with enhanced performance values. Even though organic solar cells cannot compete with conventional solar cells in terms of efficiency and long-term stability yet, they have reached the point of industrial application due to a range of unrivaled advantages. Apart from their light weight and their highly tunable optical and mechanical properties, organic solar cells can be produced in an easy and cheap, solution-based way which offers the possibility of mass production via roll-to-roll processing. Their advantages play a particular role in areas not accessible for conventional solar cells, such as curved, flexible or transparent surfaces as well as mobile devices. In our work, we investigate novel material systems used to increase the performance of organic solar cells in terms of efficiency as well as long-term stability. Here, we present insights into the correlation of optical and morphological properties of polymer-based organic photovoltaics by combining real-space imaging and X-ray scattering techniques with optical spectroscopy.
