Fraunhofer ISE Sets New Efficiency Records for Tandem Photovoltaic Modules
Fraunhofer ISE has developed two tandem photovoltaic modules achieving record efficiencies of 34.2% for a III-V germanium module and 31.3% for a III-V silicon module. These advancements were made possible through collaborations with AZUR SPACE and temicon, among others, and demonstrate potential applications in both cost-effective and high-performance solar technologies.

Fraunhofer ISE achieved record efficiencies with two tandem photovoltaic modules: a III-V germanium module at 34.2% and a III-V silicon module at 31.3%. The germanium module, part of the 'Vorfahrt' project, was developed with AZUR SPACE and features advanced anti-reflection structures from temicon.
The silicon module was produced under the 'Mod30plus' project and represents a small-scale production breakthrough. The projects involved numerous partners and were funded by the German Federal Ministry for Economic Affairs and Energy. These technologies aim to bridge gaps between conventional and high-performance solar cells.
