Large area inkjet printing for organic solar cells and OLEDs using non-halogenated ink formulations
conference paper
Transferring lab-scale processes of organic electronics to large area roll-to-roll production requires the use of up-scalable deposition techniques. Furthermore, industrial production demands the omission of halogenated and other harmful solvents. Here we discuss the solution processing of organic light emitting diodes (OLEDs) or organic photovoltaics OPV applying halogen free ink formulations that are compatible with large area iniget printings. We demonstrate the inkjet printing of the emissive layer in smOLED devices and the photo-active layer in OPV. In both cases homogeneous layer thicknesses were obtained, yielding a uniform light emission from the printed smOLEd device. While in the case of the smOLED device the luminous output was slightly lower than that of a spin coated device, the photoactive layer printed for an OPV from the halogen free ink showed similar performance as a layer spin coated from chlorinated solvents.
