The present invention relates to a novel composition comprising an organic semiconductor (OSC) and one or more organic solvents. The composition is solid at a temperature of 25 ° C., fluid at a higher temperature, and the boiling point of the solvent is 400 ° C. or less. Furthermore, the present invention relates to the use of these compositions as inks for making organic electronic (OE) devices, in particular organic photoelectric conversion (OPV) cells and OLED devices, OE devices using novel compositions. OE devices, OLED devices, and OPV cells made from such methods and compositions are described. |
