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.

Juan Francisco Martínez Sánchez Wins the Gips-Schüle Young Scientist Award for his Development of a High-Efficiency PV Hybrid Concentrator Module

Juan Francisco Martínez Sánchez, a researcher at the Fraunhofer Institute for Solar Energy Systems ISE, received the Gips-Schüle Young Scientist Award this week for combining concentrator PV technology with a conventional silicon photovoltaic (PV) module. The decisive innovation is that the hybrid PV module uses not only direct sunlight, which is concentrated by lenses onto miniature concentrator solar cells no bigger than several millimeters in size, but also diffuse, or scatttered, sunlight thanks to silicon solar cells. With this innovative concept, a bifacial PV module was able to achieve a power output of 350 watts per square meter for the first time worldwide.
