The development of complex functional materials poses a multi-objective optimization problem in a large multi-dimensional parameter space. Solving it requires reproducible, user-independent laboratory work and intelligent preselection of experiments. However, experimental materials science is a field where manual routines are still predominant, although other domains like pharmacy or chemistry have introduced robotics and automation long before. Human interaction in the process of data acquisition is seen critical due to incomplete assessment of meta-data or hidden processing correlations which complex reproducibility. Materials Acceleration Platforms (MAPs) are regarded as an enabling technology for Big Data Material Approaches, leading to an increased number of concepts and a dynamic evolution of MAP lines. In this talk, I will present our approach to laboratory automation in materials science with a strong focus on fully functional devices. AMANDA (Autonomous Materials and Device Application Platform - www.amanda-platform.com) was developed as a generic platform for distributed materials research comprising a self-developed software backbone and several MAPs. One of them, LineOne (L1), was specifically designed to produce and characterize solution-processed thin-film devices like organic solar cells. The unprecedented data quality of LineOne, in combination with Gaussian Process regression (GPR), allowed us to identify hidden process-functionality correlations which are not accessible with other methods. In between, LineOne has gained predictive power for the performance and stability of photovoltaic devices. In the next step, Bayesian Optimization will be implemented in order to transform LineOne into an autonomously acting MAP for solar cell device optimization.


Christoph J. Brabec received his PhD (1995) from Linz University, Austria. After a postdoc period under Serdar Sariciftci and Alan Heeger, he joined the SIEMENS research labs (project leader) in 2001, Konarka in 2004 (CTO), Erlangen University (full professor) in 2009, ZAE Bayern e.V. (scientific director, board member) in 2010, Interdisciplinary Center for Nanostructured Films (spokesman) in 2013 and became director at FZ Jülich (IEK-11) in 2018. His research interests include all aspects of solution processing organic, hybrid and inorganics semiconductor devices with a focus on photovoltaics and renewable energy systems
