Press Release

The Fraunhofer Institute for Solar Energy Systems ISE, supported by PSE Projects GmbH, has been publishing the PV Report on a regular basis for the past decade. The report contains a compilation of the most important facts on photovoltaics (PV) in Germany, the European Union and worldwide, documenting, in particular, the development of the photovoltaic market, solar cell and module efficiency as well as the prices over the last decades. The latest edition is freely available on the Fraunhofer ISE website as of today.

The use of hydrogen holds great potential for decarbonizing industry and thus makes an important contribution to protecting the climate. Innovative hydrogen technologies are the key to a promising and growing market. The state of Thuringia is therefore supporting the new hydrogen application center at the Erfurter Kreuz research campus “Industrial Hydrogen Technologies Thuringia (WaTTh)” with 6.9 million euros over three years. The state is providing a further 3.4 million euros for the purchase of a building in which Fraunhofer IKTS researchers can develop and test hydrogen technologies.

Floating photovoltaic power plants can contribute to the expansion of renewable energy without taking up land. The Fraunhofer Institute for Solar Energy Systems ISE, RWE Renewables and the Brandenburg University of Technology Cottbus-Senftenberg (BTU) are working together to further develop this innovative technology with other partners. In the joint research project PV2Float, the partners are to test several floating PV systems with different structure designs under real conditions over a three-year period. An Evaluation for a suitable open pit lake for the implementation is currently ongoing.

Fraunhofer Energy Research has a new location: the showroom "ENIQ - Energy Intelligence by Fraunhofer" located on the EUREF campus in Berlin. The facility functions as an interactive platform to serve the transfer of knowledge. Stake-holders from business, politics and society can discuss relevant topics with sci-entists, initiate projects and create innovations. Event formats for different tar-get groups are complemented by an exhibition area where innovative demon-strators and exhibits from Fraunhofer Energy Research are on display.

In addition to the classical applications for solar cells on roofs and open spaces, photovoltaic devices can also be used with laser light for efficient power transmission. At the 48th IEEE Photovoltaic Specialists Conference, researchers from the Fraunhofer Institute for Solar Energy Systems ISE recently presented how they were able to achieve a record conversion efficiency of 68.9% with a photovoltaic cell under monochromatic laser light. For this, the research team used a very thin photovoltaic cell made of gallium arsenide and applied a highly reflective, conductive mirror on the backside.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE have presented the newest edition of their study on the levelized cost of electricity (LCOE) of renewable power plants. The fifth edition of the study analyzes the current costs and forecasts the future cost development up to 2040 based on technology-specific learning rates and market scenarios. "Wind and solar power plants in Germany have significantly lower LCOE costs than conventional power plants. Due to the rising price of CO2 certificates, the cost competitiveness of even existing coal and gas-fired plants will further decrease in the coming years," says project head Dr. Christoph Kost.

TotalEnergies announced the launch of the e-CO2Met project at the Hydrogen Lab Leuna together with the electrolyser manufacturer Sunfire, the Fraunhofer Center for Chemical-Biotechnological Processes CBP and the Fraunhofer Institute for Microstructure of Materials and Systems IMWS. Methanol can be produced from low-carbon hydrogen and captured carbon dioxide, which is an important approach to reducing climate-damaging greenhouse gas emissions. With the ambition to produce climate-neutral methanol on site, this demonstration project will integrate the various components required to this end, such as the use of renewable energy.

The contamination of solar modules by dust and sand causes significant yield losses in the increasing use of photovoltaic systems in desert regions. In his doctoral thesis, Dr. Klemens Ilse from the Fraunhofer Institute for Microstructure of Materials and Systems IMWS researched the causes, analyzed the magnitudes and developed solution strategies. For this he was awarded the Schott AG Materials Prize.

In a brief study, scientists in the Energy Systems Analysis department at Fraunhofer ISE recently evaluated the data of photovoltaic systems registered in the Market Master Data Register (MaStR) and the master data set for subsidized systems. An important finding of the analyses is that the largest growth in PV capacity is taking place in the sector of rooftop PV systems larger than 100 kW. This sector accounts for 38 % of new PV systems. Also interesting is that 22 % of the newly installed PV systems are oriented to the west, east or east-west, and 19 % of these systems have tilt angles smaller than 20 degrees.

After completion in 2017, the city administration building "Rathaus im Stühlinger" in Freiburg was measured and analyzed in detail during the first years of operation. The good news is that the targets set in the planning phase agree with the actual consumption data to a large extent. The building and the building systems are highly efficient. In a yearly balance, the total energy consumption for the building conditioning (heating, ventilation, lighting, domestic hot water heating) is met almost entirely by the renewable energy produced onsite. Thus, the goal of achieving a net zero energy building has been achieved.
