Around the world, there is a lack of comprehensive medical care for people living in remote areas. Researchers at the Fraunhofer Institute for Solar Energy Systems ISE and the Fraunhofer Institute for Surface Engineering and Thin Films IST have devised a solution for this in the PreCare project: a flexible, modular health platform with solar power supply that can be installed on the bed of a pickup truck. It is already in use in South Africa and Namibia. The team was presented with the Innovations for a Better Future award from the Fraunhofer-Zukunftsstiftung (Fraunhofer Future Foundation) for this development.

In a joint research effort, scientists from King Abdullah University of Science and Technology KAUST and Fraunhofer Institute for Solar Energy Systems successfully replaced spin-coating with blade-coating in the production of perovskite-silicon tandem solar cells. In a “hybrid route” combining evaporation and blade-coating to deposit perovskite solar cells on silicon bottom cells, they produced tandem solar cells with efficiencies approaching 28 percent. Their result opens a path to the large-scale production of this promising new solar cell technology.

Together with the company III/V-Reclaim, scientists at the Fraunhofer Institute for Solar Energy Systems ISE have succeeded in producing high-quality indium phosphide on gallium arsenide substrates (InP-on-GaAs wafers) with up to 150 mm diameter. These new wafers can effectively replace classic indium phosphide in a variety of applications, offering a scalable pathway to lower cost. The research team developed a process to deposit a thin layer of high-quality InP on GaAs. Following a special surface treatment, these wafers are delivered epi-ready, enabling customers to directly grow III-V epitaxial structures and manufacture high-performance InP-based semiconductor devices.

The Port of Rotterdam and the Fraunhofer Institute for Solar Energy Systems ISE are working with Australian partners to investigate opportunities for Western Australia to become a world-class producer, user and exporter of renewable hydrogen. Western Australia could provide for a substantial portion of the European demand for hydrogen in 2050. The TrHyHub Study, a collaboration between key stakeholders in Australia, Germany, and the Netherlands, analyzed the critical components that could deliver a supply chain from the Mid West Hydrogen Hub in Oakajee to Germany via the Port of Rotterdam. In the short term, ammonia is the most suitable option, with substantial cost savings to be anticipated in the future.

As part of the "SPHINX" research project, the Fraunhofer Institute for Solar Energy Systems ISE has set up a pilot line for PV roof tiles at Module-TEC in Freiburg. The flexible, automated production allows the project partner Freesuns, a Swiss solar roof manufacturer, to produce its newly developed matrix shingle roof tiles on a pilot scale before moving into mass production. The production line will manufacture a total of 4,000 solar roof tiles using the matrix shingle technology. Since March 2025 the first 800 modules have been produced. Freesuns is currently installing the first roof systems into 5 existing buildings in Switzerland. The new solar roof tiles are on exhibit from May 7 - 9 at Smarter E Europe / Intersolar at the Fraunhofer ISE booth in Hall A1.
