The Fraunhofer Institute for Solar Energy Systems (ISE) is no stranger to solar power records, and it’s just set another one.
Via its own III-V germanium solar PV module, the institute reached 34.4 percent solar module efficiency. The solar record march goes on.
“The solar cells were developed by AZUR SPACE, while the anti-reflective coatings on the front glass were provided by temicon. Visitors to Intersolar / The Smarter E 2026 can see the world’s most efficient PV module at Fraunhofer ISE’s booth A1.440,” Fraunhofer ISE shares.
