Fraunhofer-Institut für Solare Energiesysteme ISE
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.

Experts Focus on PV Module Reliability – Fraunhofer ISE Organizes International Workshop in Freiburg
May 30, 2014

The reliability of PV modules plays a key role in the current debate on the German energy transformation. Module lifetime and durability affect the bankability of PV installations and are major factors to consider when making investment decisions. Science and industry are working on developing innovative materials and accelerated test procedures for PV modules. On 3-4 June 2014, experts from research and industry will meet in Freiburg to discuss the newest results and developments in the field. The Fraunhofer Institute for Solar Energy Systems ISE and the Joint Research Centre of the European Commission (JRC) are the joint organizers of the event

Organic Photovoltaic Modules by the Meter – EU project partners present six meter foil at LOPEC in Munich
May 26, 2014

A solar module, six meters long and 50 cm wide, consisting of flexible organic solar cells is the result of the European research project “FabriGen,” a joint effort between six partners from four different countries. This novel power producing foil is on exhibit at the upcoming LOPEC from 27th-28th May in Munich. The module is manufactured exclusively with a roll-to-roll process. The organic solar cells do not contain the customary indium-tin-oxide and therefore have the potential to be particularly economical. The project idea targeted applications in the field of membrane architecture, which incorporates tensile membrane structures as roofs, for example, in the architectural design.

Organic PV Modules Pass Stress Test – Fraunhofer ISE presents its flexible, large-area PV module at the LOPEC conference
May 22, 2014

A completely flexible solar PV module of circa 90 square centimeters is the centerpiece of Fraunhofer ISE’s booth at the upcoming LOPEC – the International Exhibition and Conference for Printed Electronics. Because this PV module is produced without indium-tin-oxide (ITO), an expensive compound normally used in organic photovoltaics, it also saves costs. A barrier layer in the module serves as a durable encapsulation, and the module-integrated solar cells have successfully passed the accelerated humidity-temperature test for thin-film photovoltaics. The LOPEC takes place from 26-28 May in Munich.
