Durable converters that are insensitive to environmental influences are an indispensable technological component of the energy transformation with a high economic potential. In the research project "power4re" (reliable converters for the renewable energy supply), five Fraunhofer Institutes under the leadership of the Fraunhofer Institute for Wind Energy Systems IWES are working together with industry representatives on solutions to increase the reliability and robustness of inverters in PV systems and frequency converters in wind turbines. The power4re project is being funded within the framework of the internal research program PREPARE of the Fraunhofer-Gesellschaft with funds totaling 3.5 million euros.

The École Polytechnique Fédérale de Lausanne EPFL (Switzerland) and the Fraunhofer Institute for Solar Energy Systems ISE (Germany) are organizing a free webinar as compensation the SOPHIA workshop on PV Module Reliability, which was to be held this year yet was postponed due to the Corona pandemic. The presentations on May 28th and 29th will highlight expert results and experiences on the topics of reliability and degradation as well as testing innovative PV applications. Additionally a comprehensive overview of the results from the EU MSCA project Solar-Train will be given.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have presented the newest figures on the annual electricity generation in Germany. The share of renewables in the net electricity generation, that is, the amount coming from the socket, rose from 40.6 percent in 2018 to 46 percent in 2019, and surpassed the share from fossil fuels (40 percent) for the first time.

The 39th edition of the International Energy Workshop (IEW) will take place from June 29 to July 1, 2020 in Freiburg, Germany and will be hosted by the Fraunhofer Institute for Solar Energy ISE. The IEW is a leading conference for the international energy modeling community. In a world of environmental and economic constraints, energy modeling is an increasingly important tool for addressing the complexity of energy planning and policy making. The IEW provides a venue for scholars and researchers to compare modeling tools, to discuss modeling advances for emerging energy sector issues, and to observe new trends in the global energy sector.

Christopher Hebling, division director of Hydrogen Technologies at the Fraunhofer Institute of Solar Energy Systems ISE, was appointed Honorary Professor of Chemical Engineering in the Faculty of Engineering and the Built Environment at the University of Cape Town (UCT) in South Africa. Besides research and teaching, Hebling will promote the cooperation between the Fraunhofer-Gesellschaft and the South African scientific community in the fields of hydrogen and solar technologies.

The first Solar World Congress in South America takes place in Santiago de Chile from November 4 to 7, 2019. The Congress will be held by the International Solar Energy Society (ISES) together with the International Conference on Solar Heating and Cooling for Buildings and Industry of the IEA (International Energy Agency) Solar Heating and Cooling Programme (SHC). The local host is SERC-Chile (Solar Energy Research Center), a consortium of seven Chilean Universities, as well as the Fraunhofer-Chile Foundation. The Fraunhofer Institute for Solar Energy Systems ISE and the Center of Solar Energy Technologies-Fraunhofer Chile Research (FCR-CSET) participate in the congress with a booth and presentations by its experts.

In honor of her excellent research, Dr. Laura Mundt was awarded the Eva Mayr-Stihl Young Researcher Award of the Eva Mayr-Stihl Foundation. Her doctoral dissertation entitled “High-Resolution Analysis of Perovskite Absorbers in Photovoltaics” was carried out at the Institute for Sustainable Technology Systems (INATECH) of the University of Freiburg and the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg. The prize was awarded at the opening ceremony of the 2019/2020 academic year in Freiburg.

In the future electricity grid, inverters must assume greater responsibility for the grid stability due to higher feed-in of fluctuating renewables. In Freiburg at the new multi-megawatt laboratory of the Fraunhofer Institute for Solar Energy Systems ISE, power electronic devices are developed and tested according to these new functionalities. A few weeks after officially opening the new lab building in North Freiburg, a solar inverter with a nominal power of 2.5 megawatts and a maximum DC voltage of 1500 volts was tested in the accredited TestLab Power Electronics.

Photovoltaics is a young, commercially available clean energy technology, however, its origin goes back to 1839 when Edmond Becquerel first reported the effect of light on the generation of electric currents in matter. Today, photovoltaics has become a pillar of the energy system transformation. The symposium in recognition of Edmond Becquerel will be held on March 24, 2020 in Paris.

The 2nd workshop within the RAISELIFE project takes place on Thursday, 28 November in Düsseldorf, Germany. Among the speakers will be scientists from the Fraunhofer Institute for Solar Energy Systems ISE who will talk about the durability of CSP mirrors and absorber coatings as well as the optimization of recoating intervals.
