Simon Ternes obtained his Master's degree in Physics from the University of Heidelberg in Germany (2017), where he worked on bar-coating of perovskite solar cells in Prof. Yana Vaynzof’s group. He completed his PhD thesis ‘In Situ Characterization and Modelling of Drying Dynamics for Scalable Printing of Hybrid Perovskite Photovoltaics’ at Karlsruhe Institute of Technology (2022) under the supervision of Prof. Wilhelm Schabel, Prof. Bryce S. Richards and T.T. Prof. Ulrich W. Paetzold. One year later, Simon was granted the Marie SkÅ‚odowska-Curie fellowship, ‘An intelligent perovskite solution printing line’, in cooperation with Prof. Alessio Gagliardi (Technical University of Munich, Germany) and Prof. Aldo Di Carlo (University of Tor Vergata, Italy) which he conducts at CHOSE since 2023.

Research Activity

The work of Simon Ternes focuses on in situ characterization and advanced modelling concepts for enhancing process control of large-scale perovskite printing. In particular, he is interested in non-invasive, rapid optical haracterization techniques such as reflectance, absorption and photoluminescence for developing data-intensive models of perovskite drying and crystallization processes to address the challenges of scaling and reproducing hybrid perovskite solar cell fabrication.
