German researchers set new solar efficiency records with tandem modules, surpassing silicon limits.
Researchers at Germany’s Fraunhofer ISE have set new world records for solar module efficiency, achieving 34.2% with a III-V germanium tandem module and 31.3% with a III-V silicon tandem module.
Both use multi-junction cells and advanced anti-reflective glass coatings to reduce light loss.
The breakthroughs, part of the Vorfahrt and Mod30plus projects, aim to bring high-efficiency solar technology to space-constrained rooftop and terrestrial applications, surpassing the 29.4% theoretical limit of single-junction silicon cells.
