Morphological investigations of fullerene-free bulk heterojunction blends for photovoltaic applications cast on curved surfaces — •Seraphin Aeschbach, Sebastian Grott, and Peter Müller-Buschbaum — TU München, Physik-Department, LS Funktionelle Materialien, 85748 Garching, Germany

Conventional solar cells have several drawbacks in comparison to bulkheterojunction solar cells, because this kind of new solar cells based on organic compounds are light weight, flexible, semi-transparent and easier to process, which opens a large range of applications. So this type of solar cells present a promising alternative to commonly used inorganic solar cell devices. Since the overall energy consumption around the world is steadily increasing, the interest in transportable power generating devices is enforcing the research in a wide field. Due to the outstanding properties of organic photovoltaics we want to investigate the behavior of such devices on fibers. Thereby, we want to study the influence of the curved fiber surface on the inner morphology of the organic photoactive layer via grazing-incidence wide-angle X-ray scattering and relate the obtained results to current density-voltage curves and absorbance to improve the performance.
