I am quite convinced that slot-die-coating technologies are a key strategy for bringing thin-film emerging technologies to an accelerated market entry. For this reason, I took on the challenge by joining FOM technologies to support their scientific and development efforts.

Industry partner leader and project manager on Capitano, a Federal Ministry for Economic Affairs and Energy (BMWi, Germany), 5.2 MEUR awarded project for the market entry acceleration and commercialization of a combination of emerging and disrupting technologies together with CIGS PV modules for reducing the Levelized Cost of Electricity.Industry partner leader and project manager on PERCISTAND, an EU HORIZON ca. 5.0 MEUR awarded multinational project aiming for accelerated market entry and development of innovative materials and processes for all thin perovskite on chalcogenide tandem appliances. Co-authored techno-economic study “Beyond silicon: thin-film tandem as an opportunity for photovoltaics supply chain diversification and faster power system decarbonization out to 2050,” an ex-ante estimation of the cost and greenhouse gas emissions of tandem PVs manufactured in the EU, China, and the USA as compared to mainstream single-junction silicon devices produced in China. This study is being considered for publication in Nature Energy, the second most prestigious peer-reviewed energy scientific journal worldwide.Directed an elite R&D team for the IP scouting and generation to solve existing parasitic energy losses directly affecting the levelized cost of electricity and longevity of production PV modules, influencing the revenue stream. The project yielded worldwide first detailed microscopic understanding of patterning-related losses in thin-film solar modules by application of cutting-edge metrology techniques (hyper-spectral PL and EL) and lab-to-fab proof of concept for the first-of-its-kind application of photolithography on full-size CIGS solar modules to mitigate module interconnection power losses.Technology expert team member for strategic mergers and acquisitions (M&A) due-diligence task force on multimillion-dollar investment plan.First author on two industry papers published in peer review journals.
