The present invention relates to novel compositions comprising an organic semiconductor (OSC) and one or more organic solvents. The composition is solid at a temperature of 25° C. and fluid at a higher temperature and the boiling point of the solvent is at most 400° C. Furthermore, the present invention describes the use of these compositions 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 compositions, and to OE devices, OLED devices and OPV cells prepared from such methods and compositions.
