Embodiment 1
[0427] Basically, Comparative Example 1 was repeated. However, a formulation containing 3-phenoxytoluene + 20% ethyl benzoate was used.
[0428] Formulation samples were prepared as follows:
[0429]
[0430] in 10-1000s -1 Viscosity was measured at 3.9 mPas using an AR G-2 rheometer parallel plate geometry using a Newtonian fit over the shear rate range of .
[0431] Using the same pulse width (2.2 μs), stable droplet formation can be obtained at speeds between 1-7 m / s.

Abstract
The present invention relates to novel compositions comprising an organic semiconductor (OSC) and an organic solvent. The composition comprises at least two organic solvents. 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, and relates to methods for the preparation of OE devices using novel formulations, as well as the OE devices, OLED devices and OPV cells prepared from the composition.
Description
technical field [0001] The present invention relates to novel compositions comprising organic semiconducting compounds (OSC) and organic solvents and to the use of said novel compositions as conductive inks for the preparation of organic electronic (OE) devices, especially organic photovoltaic (OPV) cells and OLED devices , to methods of making OE devices using novel formulations, and to OE devices and OPV cells made from these methods and compositions. Background technique [0002] When fabricating OE devices with high resolution such as OLEDs, OFETs or OPV cells, the OSC layer is usually applied using vapor phase techniques. However, these techniques are expensive, waste OSCs, have limited production scale, and thus prevent easy and cheap mass production of these devices. [0003] Applying layers on substrates with high resolution using conventional inkjet printing techniques results in low quality finished products. Although there are many documents disclosing inkjet pr...
