Fraunhofer ISE (original) (raw)
R&D for Energy Transition
The Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, Germany is the largest solar research institute in Europe.
With a staff of about 1 400, we are committed to promoting a sustainable, economic, secure and socially just energy supply system based on renewable energy sources. We contribute to this through our main research areas of energy provision, energy distribution, energy storage and energy utilization. Through outstanding research results, successful industrial projects, spin-off companies and global collaborations, we are shaping the sustainable transformation of the energy system.
In the market-oriented business areas of Photovoltaics: Materials, Cells and Modules, Photovoltaics: Production Technology and Transfer, Solar Power Plants and Integrated Photovoltaics, Electrical Energy Storage, Power Electronics and Grids, Climate-Neutral Heat and Buildings, Hydrogen Technologies as well as System Integration, the Institute develops materials, components, systems and processes. For this purpose, we have an excellent laboratory infrastructure at our disposal. In addition, we perform analyses, carry out studies, provide consultations and offer our clients testing and certification procedures. Fraunhofer ISE is certified according to the quality management standard DIN EN ISO 9001:2015 and according to the standard DIN EN ISO 50001:2018 for energy management.
