New World Record for Concentrator Photovoltaics – 36.7 Percent for New Solar Module Using Highly Efficient Multi-Junction Solar Cells
Jul 14, 2014

The Fraunhofer Institute for Solar Energy Systems ISE has been successfully developing concentrator photovoltaic (CPV) technology for many years. In this technology Fresnel lenses are used to bundle sunlight and focus it onto miniature, highly efficient solar cells. The FLATCON® module technology originates from Fraunhofer ISE and is continually under further development at the Institute. Now with their newest CPV module technology, the Freiburg researchers announce a world record module efficiency of 36.7 %, achieved by adapting the concentrating lens to a new solar cell structure. The high module efficiency was measured under Concentrator Standard Testing Conditions, or CSTC, and marks the best value ever achieved for a photovoltaic module.

Online Energy Charts Make German Energy Transformation Transparent for All – Fraunhofer ISE launches online comprehensive energy database
Jul 02, 2014

The Fraunhofer Institute for Solar Energy Systems ISE now provides online electrical energy data for Germany promptly and free-of-charge. “By making the data available on this website, it is our intent to promote transparent and objective discussions relating to all factors regarding the energy transformation in Germany,” says Professor Eicke Weber. Interactive data charts, which can be individually tailored by the user, display the power produced in Germany from all conventional and renewable sources as well as import and export data. This comprehensive database is now available online: www.energy-charts.de.

Electronics for Power Engineering – Fraunhofer ISE Follows New Paths with High Voltage Silicon Carbide Power Devices
Jun 03, 2014

Thanks to new components, power electronic converters for power engineering applications are becoming even more efficient. Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have now successfully implemented silicon carbide (SiC) devices with a blocking voltage of 10 kV in a DC-DC converter for medium-voltage applications. This demonstrator can be used in renewable power plants which are gaining significance for the energy grid of the future.
