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 be time‐consuming and 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.
