Excellent wind potential, strong government support, and other favorable factors could make Ireland a key player in the hydrogen economy. This is the conclusion of the HYreland project, which analyzed the technological, economic, and environmental potential for green hydrogen and its synthesis products on the island. For exports to Germany, the most favorable option is via pipeline transport to the ports of Rotterdam or Stade, provided it is available.

Road freight transport is one of the largest sources of CO2 emissions in the German transportation sector; heavy-duty transport accounts for about one-third of transportation-related greenhouse gas emissions. To enable the transition to battery-electric trucks, the necessary charging infrastructure must be available. In many cases, the power available at the grid connection is insufficient for this purpose. The Fraunhofer Institute for Solar Energy Systems ISE conducted a comprehensive feasibility study on behalf of Streck Transportgesellschaft to assess the potential for electrifying an electric truck fleet at the logistics center. According to the study, combining a photovoltaic system, battery storage, and energy management ensures a reliable power supply and represents the most cost-effective solution for logistics centers.

By applying a perovskite cell just 500 nanometers thick onto a conventional silicon solar cell, the theoretical efficiency limit increases from 29.4 to 43.3 percent. To pave the way for the industrial implementation of this tandem technology, the Fraunhofer Institute for Solar Energy Systems ISE opened a new laboratory today. The “Pero-Si-SCALE” offers an independent R&D infrastructure and is available to the German and European photovoltaic industry. In particular, solar cell and module manufacturers can use it to scale up new cell designs to large cell formats using industry-standard manufacturing processes, analyze them extensively, and integrate them into PV modules.

Scientists at the Fraunhofer Institute for Solar Energy Systems ISE have succeeded in creating colored films with transparent cutouts, thereby producing realistic-looking designs on photovoltaic modules. In this way, roof tiles, for example, can be imitated. The film cutout patterns utilize MorphoColor® technology, an invention of Fraunhofer ISE that creates a color impression without significantly impairing the efficiency of a PV module. Visitors to The Smarter E / Intersolar 2026 can view PV modules equipped with “ShadeCut” at the Fraunhofer ISE booth A1.440.

Setting up a manufacturing facility or developing new technologies – NEXUS GreenTech, the new spin-off of the Fraunhofer Institute for Solar Energy Systems ISE, supports manufacturers of wafers, solar cells, and PV modules with issues related to product development and factory planning. The founders, Dr. Jochen Rentsch, Dr. Sebastian Nold, and Dr. Nico Wöhrle previously spent many years researching PV technologies, associated production processes, and quality assurance, and all three were most recently part of the PV Technology Transfer unit at Fraunhofer ISE. The spin-off, founded at the end of March, is headquartered in Freiburg, Germany.
