The Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) in Germany, in partnership with US Source Energy, has developed a series of silicon-based PV modules for satellites. This product line combines silicon-based cells with shingled matrix interconnection technology and automated manufacturing, aiming to provide a low-cost solution for low Earth orbit (LEO) satellites as an alternative to the currently expensive and supply-constrained III-V PV technology used in space applications.
