Fraunhofer Institute for Solar Energy Systems ISE

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 1400, 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 business areas of Photovoltaics, Energy Efficient Buildings, Solar Thermal Power Plants and Industrial Processes, Hydrogen Technologies and Electrical Energy Storage as well as Power Electronics, Grids and Smart Systems, 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.

Efficient Mass Production of Fuel Cells

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE are currently optimizing the large-scale production of proton exchange membrane fuel cells (PEMFC). Within the joint project "TiKaBe", innovative catalyst inks for use in different industrial coating processes are being developed. In a second re-search project called "BI-FIT", the focus is on shortening and simplifying the break-in procedure, during which the initial conditioning of fuel cells takes place. The researchers will be presenting current insights into their work at the international expo and conference hy-fcell from September 13-14, 2023 in Stuttgart. At Booth 4D55, the institute will be showing membrane electrode assemblies (MEAs) for heavy-duty applications as well as work on cell compo-nent characterization and lifetime testing.

New Project “HybridKraft” Launched: PV Electricity Shall Increase Efficiency of Solar Thermal Power Plants

The hybrid combination of solar thermal power plants, photovoltaics and storage promises cost-effective and stable electricity generation. Just such a system is to be developed in the newly launched „HybridKraft" project, funded by the German Federal Ministry of Economics and Climate Protection and headed by the Fraunhofer Institute for Solar Energy Systems ISE. The project focus is on developing an electric heater for molten salt storage tank that is suitable for large-scale power plants. Such solutions which convert renewable electricity into high-temperature heat for direct use or storage are also interesting for industrial applications.

World Record Efficiency of 15.8 % Achieved for 1 cm² Organic Solar Cell

Organic photovoltaics (OPV) opens up new areas of application for solar energy thanks to its climate friendly and inexpensive production and its flexible and potentially transparent solar cells. To help this technology achieve a market breakthrough, research institutes worldwide are working to improve the efficiency and scalability of organic solar cells. Researchers at the Fraunhofer Institute for Solar Energy Systems ISE and the Materials Research Center FMF at the University of Freiburg have now improved their own efficiency record, announced back in September 2020, for an organic solar cell with an area of one square centimeter. Now, with a new record efficiency of 15.8 percent, the research team at Fraunhofer ISE has again set the world record in this category.

Fraunhofer ISE Has a Revised Organizational Structure as of July 2023

The transformation of our energy system increasingly requires directed systemic solutions and approaches. As the largest solar research institute in Europe, the Fraunhofer Institute for Solar Energy Systems ISE has been developing solutions for a sustainable and climate-neutral energy supply for over 40 years. To better align and network within and across its research and development services on an interdisciplinary basis, Fraunhofer ISE is reorganizing its competencies in the areas of energy provision, energy distribution, energy storage and energy utilization. As of July 2023, the institute will be divided into four divisions called "Photovoltaics," "Power Solutions," "Heat and Buildings," and "Hydrogen Technologies". An additional cross-disciplinary research area entitled "System Integration" will be established.
