Influence of printing temperature on the efficiency of organic solar cells — •Linus Fidelis Huber, Kerstin Sabrina Wienhold, and Peter Müller-Buschbaum — Technische Universität München, Physik-Department, Lehrstuhl für Funktionelle Materialien, James-Franck-Str. 1, 85748 Garching, Germany

Solar cells have been a prominent and successful concept for eco-friendly energy conversion for a long time, but in search for better efficiencies and cheaper production costs, new materials and production techniques need to be explored. Printable-thin-film solar cells could lower production-cost by means of a high scale-up potential and an easier production process. They can also yield high efficiencies, are of lighter weight, flexible and semitransparent. This suggests a wide variety of possible applications, where silicon-solar cells seem to be less applicable. Printing temperature is an important parameter and varying it, could lead to better efficiencies and a broader understanding of the polymers dependence on temperature. We focus on novel low band gap polymers in combination with non-fullerene acceptor molecules. Four different printing temperatures are studied and evaluated using UV-Vis, photoluminescence, AFM and GISAXS measurements.
