Heinz Ossenbrink

Former European Commission Joint Research Centre

Dr. Heinz Ossenbrink, has a PhD in Physics from Hahn Meitner Institute, Berlin, and joined the European Commission's Joint Research Centre in 1982. He built up the JRC's activity on Photovoltaics when Europe started its research and pilot programme for Photovoltaic systems. In 1995 he became Head of the Unit for Renewable Energy, and expanded research and support activities to Energy Efficiency and Bio-Energy, notably Biofuels. His work was dedicated to the scientific support of EU legislation for Renewable Energies and Energy Efficiency. More  recently, he developed the unit's portfolio to support Africa's efforts for a renewable energy supply.

Since 1982 he contributed to the standards work of the IEC TC82, Solar Photovoltaic Systems, in particular regarding calibration of reference cells and lifetime testing of PV modules. His many publications cover measurement and testing methods for photovoltaic generators, economic assessment of renewable energy and global environmental impacts of extended bio-fuel use.

Heinz Ossenbrink has been serving in the Scientific Committees and in Chair person functions of leading scientific conferences, such as the prestigious series of European Photovoltaic Solar Energy Conferences and the European Biomass Conferences.

Wim Sinke

Program Development Manager, TNO Energy Transition, The Netherlands

Wim Sinke (1955) is Program Development Manager at ECN Solar Energy, Petten, The Netherlands. He studied experimental physics at Utrecht University, where he graduated in 1981. He did PhD research at the FOM-Institute for Atomic and Molecular Physics (AMOLF) in Amsterdam and received a doctor’s degree from Utrecht University in 1985 for a thesis entitled “New physical processes for silicon solar cells”. From 1986 to 1987 he was a visiting scientist at the Hitachi Central Research Laboratory in Tokyo, where he worked on amorphous silicon. From 1987 to 1990 he was project leader at AMOLF and was involved in crystalline silicon solar cells and fundamental properties of amorphous silicon, as well as in ion and laser processing of semiconductors. In 1990 he joined the Energy research Centre of the Netherlands ECN to set up and lead a new group on photovoltaics. This group has grown to a size of 80 people and covers a broad range of topics: wafer-based crystalline silicon, thin-film silicon, and polymer solar cells and modules, including life-cycle and economic analyses.

Wim Sinke is a part-time professor at Utrecht University on “Science and Applications of Sustainable Energy Systems” and Chairman of the European Photovoltaic Technology Platform. He has received several prestigious awards, including the Royal Dutch Shell Prize 1999 for his contributions to the science and technology of silicon and solar cells and for his role in the creation and development of the Dutch programme on R&D and implementation of photovoltaics, and the European Becquerel Prize 2011 for outstanding merits in photovoltaics.
