The Fraunhofer Institute for Solar Energy Systems ISE has announced developments in specialized solar module technologies. In early August, Fraunhofer ISE and the U.S.-based company Source Energy introduced a line of silicon-based solar modules designed for low-Earth-orbit satellites. These modules utilize a shingle-matrix interconnection to maintain electrical continuity despite potential damage from debris. The technology aims to provide a lower-cost, robust alternative to traditional III-V solar technology for commercial satellite missions. Later in the month, researchers at Fraunhofer ISE and the University of Freiburg reported progress in scaling semitransparent organic photovoltaic (OPV) modules. ~~By utilizing~~ Using industrially viable slot-die coating and sputtering processes, the team produced 14.5 by 14.5 centimeter modules with up to 9.26% efficiency and an average transparency of 43.2% ~~transparency.~~ in the visible spectrum. This technology utilizes carbon-based semiconductors and can be applied to glass or foil to create flexible modules. The development is intended for ~~use in~~ applications where solar cells act as translucent elements, such as building facades, greenhouses, ~~and~~ car roofs, or tinted glass surfaces. Dr. Uli Würfel, head of the Organic and Perovskite Photovoltaics department at Fraunhofer ISE, noted that scaling up to large areas is a major challenge, as laboratory results often fail to translate directly to industrial manufacturing processes.
