Fraunhofer-Institut für Solare Energiesysteme ISE
Solar Cell Contacts From Tubes – Innovative Fine Line Metallization Technology Promises Higher Efficiency Values
Oct 16, 2014

Together with industrial partners MERCK, HERAEUS and ASYS, researchers from the Fraunhofer Institute for Solar Energy Systems ISE have developed innovative new materials and contactless techniques for applying ultrafine, homogeneous contact fingers to solar cells. This ‘dispensing’ technology can be easily integrated into conventional silicon solar cell production lines where it replaces screen printing as the method of applying front side metallization: Consequently material usage is reduced, contact fingers are thinner and more of the semiconductor surface area is exposed to sunlight, which results in increased current collection and relative improvements in efficiency of around two percent. The new technology can also be used to optimize further production steps in solar cell manufacture.

Innovation under the Scandinavian Sun – Building Integration of Polymeric Solar Collectors Demonstrated
Oct 10, 2014

In the joint European project “SCOOP” (Solar COllectors Made Of Polymers), a consortium, led by the Fraunhofer Institute for Solar Energy Systems ISE, has developed polymeric solar collectors that combine functionality, cost efficiency and aesthetics. The solar demonstration system of the project partner Aventa meets over 60 percent of the hot water and space heating demand for the 34 terraced houses, which are built to passive house standards. The new heating system was presented to the public in October 2014.

Fraunhofer ISE Leads in Precision Tests for PV Modules – Measurement Accuracy in the “CalLab PV Modules” Now at a Record 1.6 Percent
Oct 08, 2014

The calibration laboratory of the Fraunhofer Institute for Solar Energy Systems ISE has optimized its precision measurements even further. After performing comprehensive analyses, “CalLab PV Modules” was able to improve its measurement precision of PV module performance tests to 1.6 percent. A round robin event carried out among the internationally leading calibration laboratories (NREL in USA, AIST in Japan and JRC in Italy) confirmed the exceptional reproducibility of the measurements. Thus, Fraunhofer ISE once again strengthens its technological lead in the precision of electrical performance measurements of PV modules.

Dr. Stefan Glunz Receives Becquerel Prize – EU Commission Honors Pioneering Work on High Efficiency Solar Cells
Sep 22, 2014

Since 1989 the European Commission has awarded the Becquerel Prize to distinguish outstanding merits in photovoltaics. This year the prize was awarded to Dr. Stefan Glunz, division director of “Solar Cells – Development and Characterization” at the Fraunhofer Institute for Solar Energy Systems ISE. The prize committee honors Stefan Glunz for his excellent pioneer work in the area of high efficiency silicon solar cells and his contribution to the worldwide success of photovoltaic electricity generation. The prize was presented on September 22, 2014 at the European PV Solar Energy Conference (EU PV-SEC) in Amsterdam.

“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.
