  • Following the Bundestag’s decision of June 2021 on the Climate Protection Act (KSG), which tightened climate regulations and moved the goal for climate neutrality in Germany to 2045, the Fraunhofer Institute for Solar Energy Systems ISE recalculated the results of its study "Pathways to a Climate-Neutral Energy System" with its energy system model REMod. The Institute works with four scenarios to analyze the effects of societal trends on achieving the climate targets. The results show that the reduction targets are still achievable by 2045, but along different paths and at different costs.

  • This year the Fraunhofer Institute for Solar Energy Systems ISE celebrates its 40th anniversary. As the largest solar research institute in Europe with currently around 1300 employees, Fraunhofer ISE has been contributing to Germany’s energy transition since it was founded in 1981. Today, the institute has become a major global trailblazer and research partner for an energy supply based on 100 percent renewable energy.

  • The Fraunhofer Institute for Solar Energy Systems ISE is developing refrigeration circuits for heat pumps which shall operate as efficiently as possible with low amounts of the climate-friendly refrigerant propane. This research is carried out in project “LC150 - Development of a Refrigerant-reduced Heat Pump Module with Propane”, funded by the German Federal Ministry for Economic Affairs and Energy BMWi. In an automated cross-evaluation, a team from the institute is testing various components of heat pumps on the large scale, in which dozens of component combinations under different operating parameters are investigated. The main objectives are to further reduce the volume of required refrigerant, to identify methodological correlations and to obtain data for the simulation of heat pump design. The measurement campaign collects an abundance of parameter variations 24/7 over one year, thus generating a unique database.

  • M10 Industries AG and the Fraunhofer Institute for Solar Energy Systems ISE and have developed a matrix shingle concept for connecting silicon solar cells and a new stringer for manufacturing novel matrix shingle modules. The stringer, which arranges the shingle solar cells offset from each other similar to bricks in a masonry wall, was built within the Shirkan project, funded by the German Federal Ministry for Economic Affairs and Energy (BMWi). This shingle arrangement results in increased efficiency, a homogeneous appearance and improved shading tolerance of photovoltaic modules. The first prototypes for matrix shingle modules will be shown by Fraunhofer ISE at Intersolar Europe Restart 2021 (October 6-8, Messe München, Booth A6.370).

  • A heavy-duty truck weighing 18 tons and equipped with a 3.5 kilowatt-peak photovoltaic system is now driving on Germany's roads. The commercial vehicle with integrated high-voltage photovoltaic system and feed-in to the 800-volt traction battery has been approved for road traffic. The solar power produced directly on the vehicle can cover 5 to 10 percent of the truck's energy needs. In the Lade-PV project, the Fraunhofer Institute for Solar Energy Systems ISE, with its project partners from industry and the Fraunhofer Institute for Transportation and Infrastructure Systems IVI, has developed solar PV modules and power electronics for integration in commercial vehicles. This truck, the first equipped with these PV modules, has now passed the technical inspection, marking a milestone towards more climate-friendly road freight transport.

  • As part of the project “APV-Obstbau”, BayWa r.e. and the Fraunhofer Institute for Solar Energy Systems ISE have cooperated with other research partners to set up an agrivoltaic system for research purposes at the “Bio-Obsthof Nachtwey” in Gelsdorf, Rhineland-Palatinate. It is the first system of its kind in Germany. The total test area for the project covers around 9100 square meters. The agrivoltaic system, which has a capacity of 258 kWp, has been installed on approximately one third of the plot.

    Energy boost for underwater robot

    September 08, 2021

    With modern non-destructive test methods, scientist of Fraunhofer IKTS and the research group Smart Ocean Technologies (SOT) analyze the battery state of underwater robots, so-called Unmanned Underwater Vehicles (UUV). Such underwater vehicles are being used more and more frequently and for longer periods of time: they inspect drilling platforms, maintain underwater gas pipelines, search for cracks in offshore wind turbines, collect marine data or map the fauna and flora on the seabed. Better battery management should now reduce deployment costs and ensure that these underwater robots can dive for longer.

    Current-based repair process for new solar cell technologies

    August 26, 2021

    The next generation of solar cells will contribute significantly to a sustainable power supply on a global scale. For state of the art technologies such as PERC (Passivated emitter and rear cell, a team from the Fraunhofer Center for Silicon Photovoltaics CSP has now researched an active mechanism that can be used to optimize high-performance cells.

  • Power electronics in wind turbines ensure that the fluctuating energy generated is fed evenly into the grid. The materials and components used in this process are exposed to extreme stress. Together with partners, the Fraunhofer Institute for Microstructure of Materials and Systems IMWS has now developed an approach for significantly more robust solutions. The new components from the chip to the system level, tested on a megawatt test bench, reduce switching losses, improve power density and reliability, and enable a 50 percent increase in service life.

    Wind turbines with integrated electrolyzer demonstrate sustainable hydrogen production at sea

    August 19, 2021

    The offshore wind turbines of the future are set to produce molecules instead of electrons. Self-sufficient units comprising a wind turbine and an integrated electrolyzer produce green hydrogen on an industrial scale and save the costs of connection to the grid. In this way, they can make a significant contribution to the reduction of greenhouse gas emissions. In a second phase, the green hydrogen can be converted into further synthetic fuels and energy carriers. This vision is now intended to become a reality in the scope of the H2Mare flagship project funded by the German Federal Ministry of Education and Research (BMBF).
