Beschreibung
Zusammenfassung:The present invention relates to novel formulations comprising an organic semiconductor (OSC) and one or more organic solvents. The formulation comprises a viscosity at 25° C. of less than 15 mPas and the boiling point of the solvent is at most 400° C. Furthermore, the present invention describes the use of these formulations as inks for the preparation of organic electronic (OE) devices, especially organic photovoltaic (OPV) cells and OLED devices, to methods for preparing OE devices using the novel formulations, and to OE devices, OLED devices and OPV cells prepared from such methods and formulations.
