Printed low bandgap polymer films — •Xinyu Jiang and Peter Müller-Buschbaum — TU München, Physik-Department, LS Funktionelle Materialien, 85748 Garching

Printing of low bandgap polymer films is of interest in organic photovoltaics. Roll-to-roll processing and large-area processability on low cost together with flexible substrates make conjugated polymer-based organic solar cells extremely attractive as a cost-effective solution to today's energy-shortage problem. We study printed mixtures of the low-bandgap polymer PTB7 with the fullerene derivate PCBM with respect to optical absorption and electrical properties. The film structure and morphology is proved with atomic force microscopy (AFM), scanning electron microscopy (SEM) and grazing incidence small angle x-ray scattering (GISAXS).
