Prof. Dr. Arno Smets is a Professor of Solar Energy and Director of Extension School Education at Delft University of Technology. His research focuses on developing technologies to convert solar energy into electricity and artificial fuels, with a current emphasis on lightweight and flexible thin-film silicon PV technologies in collaboration with HyET Solar.

Miro Zeman serves as Professor and Head of the Electrical Sustainable Energy department at TU Delft's faculty of Electrical Engineering, Mathematics and Computer Science, where he has established himself as a leading figure in photovoltaic technology research. After earning his MSc in Materials Science and PhD from Slovak University of Technology in 1989, focusing on material structures for electronics based on hydrogenated amorphous silicon, he joined TU Delft's solar cell group. His career progression includes appointment as associate professor in 2001 and full professor in 2009, holding the chair of Photovoltaic Materials and Devices. His research focuses on developing novel materials and concepts for improving thin-film silicon solar cell performance and modeling amorphous semiconductor devices. His impact on the field is evidenced by his leadership of over 30 Dutch and 6 European projects in thin-film solar cell development, authorship of more than 270 scientific publications, and contributions to three scientific books, including "Solar Energy: The physics and engineering of photovoltaic conversion technologies and systems." Beyond academia, he co-founded the Slovak Renewable Energy Agency in 2006 to promote solar energy implementation in Slovakia, while maintaining an active presence at international conferences with over 80 presentations across Europe, USA, Japan, and China.

René van Swaaij serves as Associate Professor in the Photovoltaics Material and Devices group at TU Delft's Faculty of Electrical Engineering, Mathematics and Computer Science, where he combines research expertise in silicon-based solar cells with educational leadership as programme director of the Master's in Sustainable Energy Technology. After earning his MSc in Physics and PhD on amorphous silicon-based photoconductors for xerography from Utrecht University, he has established himself as a leading figure in photovoltaic research and education. His research focuses on the processing and underlying physics of silicon-based solar cells, particularly in thin-film technology, with significant contributions to understanding interface properties and performance enhancement of amorphous silicon solar cells. Beyond his research contributions of over 100 journal and conference papers, he has co-authored the influential book "Solar Energy: The physics and engineering of photovoltaic conversion technologies and systems" and plays a key role in TU Delft's online education initiatives, including the Solar Energy Engineering MicroMasters program. Through his teaching of semiconductor device physics at both BSc and MSc levels, he continues to shape the next generation of sustainable energy technologists while advancing the field of photovoltaic technology.
