Estimating the term…
The present invention relates to novel compositions comprising an organic semiconductor (OSC) and a wetting agent, to their use as inks for the preparation of organic electronic (OE) devices, especially organic photovoltaic (OPV) cells and organic light emitting diode (OLED) devices, to methods for preparing OE devices using the novel compositions, and to OE devices, especially OLED devices and OPV cells prepared from such methods and compositions. The efficiency of an OE device with the inclusion of 1% volatile surfactant was 13.5 cd/A at 100 cd/m2
1-16. (canceled)
A composition comprising one or more organic semiconducting compounds (OSC), one or more organic solvents, and one or more additives that decrease the surface tension of the composition (wetting agents), wherein said wetting agent is volatile and is not capable of chemically reacting with the organic semiconducting compounds.
