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.

Project SOLARX: Production of Heat, Electricity and H2 from Solar Energy

The project “Dispatchable concentrated Solar-to-X energy solution for high penetration of renewable energy (SOLARX)" ,funded by the Horizon Europe program, was launched on November 1, 2022. The main objective of the 3-year project with a total budget of 3 million euros is to demonstrate at laboratory scale the technical, economic and social relevance of the efficient synergic production of heat, electricity and hydrogen from the solar resource in a single facility. The consortium is composed of companies, technological centers, industrial partners and universities: HyGear (Netherlands), Acciona Industrial (Spain), EMD International (Denmark), Fraunhofer Institute for Solar Energy Systems ISE (Germany), Danmarks Tekniske Universitet (Denmark), Laboratoire Nanotechnologies et Nanosystèmes de la Université de Sherbrooke (CNRS, France/Canada) and accelopment Schweiz AG (Switzerland).

First Green Solar Modules Integrated into Façade of the Center for High Efficiency Solar Cells

Sixty photovoltaic (PV) solar modules with a green MorphoColor® structural layer have recently been added to the façade of the Center for Highly Efficient Solar Cells at the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg. The pilot project for building-integrated photovoltaics (BIPV) will supply the research institute with approximately 11 megawatt hours of solar electricity per year. The MorphoColor® technology developed by the research institute makes it possible to color the glass of the PV modules, while maintaining at least 90 percent of the module efficiency. The integrated photovoltaic system can either set colored accents on the building façade, as in this example, or visually blend into the building, for example, as brick red-colored PV modules on the roof.
