Description of the organisation

The Energy research Centre of the Netherlands (ECN) is the leading centre for energy research and development in the Netherlands. ECN employs around 600 staff. The energy experts are structured in business units: Solar Energy; Wind Energy; Biomass and Energy Efficiency; Environment and Energy Engineering; and Policy Studies. ECN Solar Energy offers high-level expertise in the fields of PV materials, cell processing, cell and module design and manufacturing. Our activities vary from fundamental research addressing crystalline silicon and thin-film technology to high-quality consultancy. Our technology is available for transfer to and implementation in the PV industry.

Role in the Project

ECN will play a very active role throughout the CHEETAH program as it will be the program coordinator, and will also lead WP8 on module development for ultrathin x-Si cells and thin-films. ECN has a proven track record in development of device concepts and manufacturing technology for p- and n-type silicon cells, and module technology (for example MWT) compatible with the cell developments. Until October 2012, ECN has been chairing the PV Joint Program of the European Energy Research Alliance (EERA). Moreover, ECN has coordinated and contributed to a large number of European RTD projects, a.o. as coordinator of the Integrated Project CrystalClear (28 M€ budget, 16 partners)


Key people involved

Dr. Jan Kroon  is Sr. Research Scientist and Project Manager, currently active  in the PV Module and Applications group of ECN Solar Energy. He received his M.Sc. degrees in Chemistry from the University of Amsterdam in 1987. In 1992 he graduated from the University of Amsterdam with a Ph.D. in Physical Organic Chemistry. From 1992 until 1996 he worked as a post doctoral fellow on Organic solar cells at the Wageningen University. He started his professional career at ECN in 1996, and was active in the field of Organic based Photovoltaics as programme coordinator/projectmanager and senior scientist until June 2013. He is an experienced coordinator and manager of several national and international (European)  projects.



Dr. G. Paul Wyers is director of ECN Solar Energy. He received his B.Sc. and M.Sc. degrees in Geochemistry from the University of Utrecht in 1981 and 1984 respectively. In 1987 he graduated from The Ohio State University with a Ph.D. in Geochemistry. He started his professional career at ECN in 1988, and was active in nuclear energy and environmental research, before he entered the photovoltaics field in 1997. Since 2003 he is director of ECN Solar Energy, a business unit with 80 scientists and engineers dedicated to R&D of crystalline silicon- and thin-film PV technology. He and his unit have participated, frequently as coordinator, in many European projects. In 2010 he initiated the Joint Program on Photovoltaics within the European Energy Research Alliance EERA. He has been the coordinator of this program from its start until November 2012.



Paul Sommeling (MSc) joined ECN in 1996 and is researcher in the Module Technology group since 2011. He has a huge experience in durability testing and module encapsulation, and participated in an important number of EU projects relating to thin film PV.



Dr. Sjoerd Veenstra
Research Scientist and programme coordibnator on Polymer based PV. He has expertise in conjugated polymer physics, fabrication and characterization of polymer based PV devices. He is currently involved in projects aiming at the upscaling of laboratory cells from small areas towards high-throughput low-cost R2R manufacturing.
