22.4: Invited Paper: Tuning Solution Processed OLEDs Towards R2R Printing

Solution processed OLEDs offer the potential for highest throughput production processes such as roll-to-roll (R2R) printing. We use polymer mixtures with additives to evaluate and optimize the performance. Such multi-component systems open up a huge parameter space by varying layer thicknesses, material combinations and concentrations. Manual device fabrication would he time-consuming and e expensive. A new custom built and automated fabrication and characterization setup accelerates material screening, testing and optimization. Furthermore, a systematic set of devices is the basis for reliable comparisons with simulations.
