Fraunhofer-Institut für Solare Energiesysteme ISE
“Sustainability Summit” in Freiburg from October 13-14, 2014 – Former Solar Energy Conference Expands its Horizon
Sep 18, 2014

In terms of sustainability, the City of Freiburg in Breisgau holds a leading role internationally. Also within Freiburg’s research scene, sustainability topics form a connective link between the research at the five local Fraunhofer institutes, with over 2000 employees, and between their work with the University of Freiburg, with whom they cooperate. Sustainability in Freiburg involves both the sciences and social sciences and emphasizes that the transformation to a sustainable lifestyle not only requires technological solutions but also public acceptance and suitable legal and economic boundary conditions.

Photovoltaic Systems Generate Five Percent More Power than Expected – Fraunhofer ISE Identifies New Data Base for Yield Predictions
Sep 15, 2014

PV systems in Germany are regularly generating higher yields than expected. An investigation by Fraunhofer ISE links these higher yields to an upward trend in solar radiation, pointing out that the current radiation level in Germany is considerably higher than the average values of the last 30 years. As these average values have generally been used in yield predictions up to now, actual PV system yields are exceeding their forecasts by approximately five percent, making them more cost-effective than anticipated. To take this effect into account, Freiburg researchers have adapted their quality assurance services for PV systems and are now basing their yield predictions on solar radiation data from the last ten years.

German Energy Transformation Widely Accepted – Interdisciplinary Research Project Aims to Facilitate Germany’s Transition to Renewables
Sep 10, 2014

Under the leadership of the Fraunhofer Institute for Solar Energy Systems ISE, an interdisciplinary team is investigating how the transition to an energy system based on renewables finds durable acceptance among the German population. In addition to Fraunhofer ISE, the partners involved are the Fraunhofer Institute for Systems and Innovation Research ISI, the Center for Interdisciplinary Risk and Innovation Studies ZIRIUS at the University Stuttgart and the Institute for Political Science at the University of Münster (WWU). Public utilities and other partners with practical experience in the field supplement the team. The project called “KomMA-P | Strengthening the Acceptance of the Energy Transformation” is supported by the German Federal Ministry for Education and Research (BMBF). First results show that there is a large degree of acceptance for the energy transformation within the German population.

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.
