    The growth of solar energy has been grossly underestimated in the results of the models of the Intergovernmental Panel on Climate Change (IPCC). Costs have dropped and infrastructures expanded much faster than even the most optimistic models had assumed.

    The Fraunhofer Institute for Solar Energy Systems ISE is collaborating with the Energy Research Centre of the Netherlands (ECN) to organize the 8th Back Contact Workshop, which will be held in Freiburg from November 21–22, 2017. The workshop focuses on back contact technology for solar cells and modules. This technology involves fitting the contacts entirely on the rear side of the solar cells in order to improve sunlight absorption on the front side.

    The part-time and online study program provides a great opportunity to gain insights into the science and technology of solar energy. The program, which replaced the successful "Master Online Photovoltaics" last year is now running in its second year and offers a wide variety of subjects from solar cell technologies, photovoltaic systems and grids to solar thermal systems.

    To secure water availability on an economic and ecological level, the importance of reusing community and industrial wastewater and process fluids is becoming more and more evident. The cooperative project “Treatment of Concentrates from Wastewater Recycling Processes,” or HighCon for short, aims to develop innovative, multi-step selective processes that allow the generated concentrates to be almost fully reused.

  • Silicon solar cells dominate the global photovoltaic market today with a share of 90 percent. With ever new technological developments, research and industry are nearing the theoretical efficiency limit for semiconductor silicon. At the same time, they are forging new paths to develop a new generation of even more efficient solar cells.

    Until a few years ago, solar air heating collector systems have received only limited attention on the market compared to fluid heating collector systems. Solar air heating collectors are more difficult to measure and to evaluate. This not only hinders the development of new products but also provides less transparency on existing products. In the meanwhile, a more detailed measurement method has been incorporated into the test procedure for solar thermal collectors (DIN EN ISO 9806). On this basis, Fraunhofer ISE created an MS Excel application in order to improve air collector evaluation and system planning. The calculated results serve to certify solar air collectors according to Solar KEYMARK, to design system layouts, to develop air collectors as well as to perform parameter variation studies.

  • The expansion of renewable energy sources impacts the entire energy system in a variety of ways. Both the functions of the individual components, i.e. supplier, consumer and storage, as well as their interaction with each other must be redefined. Buildings themselves will also have to take on new roles. They must be able to react flexibly to the conditions in the energy system, orienting their operation more on the energy production than demand.

  • At mid-morning today on Friday, February 24, 2017, a fire broke out in one of the laboratories of the Fraunhofer Institute for Solar Energy Systems ISE located in the Solar Info Center in Freiburg. The fire alarm was immediately set off and the building was successfully vacated. The firefighters were on location immediately and brought the fire quickly under control. According to the Fire Service, four firefighters were injured. A forensic investigation to determine the cause of the fire is underway. The building is presently closed and entry is not permitted. The Fraunhofer Institute for Solar Energy Systems ISE will report more information as it is confirmed.

    The Fraunhofer ISE Energy Charts presents up-to-date data on German electricity production using user-friendly graphs. Now an interactive map has been added that shows the locations of all power plants listed on the European Energy Exchange (EEX) in Leipzig. This new map provides a quick overview of the power plant locations and their grid connectivity.

    Prof. Dr. Hans-Martin Henning and Dr. Andreas Bett will serve as provisional institute directors of Fraunhofer ISE as of January 1, 2017 for the interim. This decision was made by the executive board of the Fraunhofer-Gesellschaft, since the appointment procedure for Prof. Dr. Eicke R. Weber’s successor has not yet been finalized. Having reached retirement age, Prof. Weber will be leaving Fraunhofer ISE at the end of 2016.

    As commissioned by the German embassy in Cairo, the Fraunhofer Institute for Solar Energy Systems ISE, in cooperation with SolarizEgypt, has calculated the electricity generation costs (LCOE) for renewable technologies and conventional power plants in Egypt. The results were published in a study and presented at a workshop at the German Science Centre Cairo. The calculations of Fraunhofer ISE show that electricity from wind and ground mounted PV systems in Egypt is already competitive today and, in part, less expensive than gas power plants and diesel generators.

    On November 11, 2016 at the Konzerthaus in Freiburg, the Fraunhofer Institute for Solar Energy Systems ISE honored Prof. Eicke R. Weber’s achievements at a scientific symposium on the global energy transformation. The list of speakers at the symposium reflects Weber’s successful networking within the photovoltaics sector and beyond. The talks presented at the Scientific Symposium on Research for the Energy Transformation have been published on our blog Innovation4E in two parts.

    Fraunhofer ISE and 7 European partners recently started a new Marie Sklodowska-Curie project in the field of photovoltaic module life time forecast and evaluation. The objective is to develop novel, validated models for the service life time and energy prediction of PV modules and systems. The SOLAR-TRAIN project will also qualify selected PhD students in the field of PV durability as part of a highly innovative, multi-disciplinary project meeting industry requirements. SOLAR-TRAIN invites applications for 14 PhD fellowships. The successful candidates will be hosted at leading European research centres and companies starting in March 2017. The deadline for applications is 11th December 2016.
