Evaluating the potential of organic photovoltaics materials and devices for industrial viability is a multi-dimensional large parameter space exploration. Manual experimentation is extremely limited in throughput and reproducibility. Automated platforms for fabricating and characterizing complete functional devices can accelerate experimentation speed within tight processing parameter variations. In this talk I will introduce the concept for the automated research platform AMANDA Line 1 and outline the R&D challenges such a research platform will be able to address in the near future in the broad scope of semiconducting materials. As a first test case I will demonstrate a multi-target evaluation of photovoltaic materials at full device level. About 100 processing variations and nearly 1000 devices have been tested for one photovoltaic absorber on AMANDA Line 1 and evaluated by a Gaussian process regression-based data evaluation. The unique data quality in combination with GPR allowed to discover hidden structure – property relationships within 70 hours only which otherwise would have taken months to establish.
