en.Wedoany.com Reported - RCT Group has announced the establishment of RCT Space GmbH, a subsidiary focused on developing crystalline silicon solar cells and modules for satellite applications, headquartered in Konstanz, Germany. The company combines terrestrial photovoltaic manufacturing expertise with satellite power systems and space qualification processes to advance crystalline silicon technology into the space sector.
The expansion of low Earth orbit (LEO) constellations, national space programs, and increasing commercial space activities are driving sustained growth in demand for satellite power systems. RCT Space states that the current supply chain for space-qualified solar cells is limited in scale, primarily relying on specialized technologies and certification processes. The company plans to apply crystalline silicon solar technology, widely used in terrestrial photovoltaic manufacturing, to the space domain, with its approach combining industrial-scale manufacturing with technologies developed for orbital radiation environments.
In the initial phase, RCT Space will focus on low Earth orbit (LEO) satellite applications. The company believes that solar cells required for such missions should be manufacturable at higher volumes, efficiently certified, and have shorter supply chain cycles compared to traditional space solar technologies.
RCT Space Chief Technology Officer Wolfgang Jooss revealed that the company is developing technology around a patented in-flight radiation annealing concept, which aims to enhance the viability of crystalline silicon cells for space missions. According to the company, laboratory validation has been completed, and the technology is expected to be certified within the next 18 months in accordance with European Cooperation for Space Standardization (ECSS) requirements.
RCT Space Chairman Peter Fath stated that with the continued expansion of satellite constellations, the company anticipates growing demand for scalable and secure solar cell supply chains. RCT Space expects to complete ECSS certification by 2027, after which it plans to commence commercial deliveries to European and international satellite operators.
