Fraunhofer ISE achieves 31.3% record solar-to-hydrogen efficiency in CPV electrolysis

Summary

Researchers at Fraunhofer ISE achieved a record 31.3% solar-to-hydrogen efficiency in outdoor testing using micro-concentrator photovoltaics coupled to proton exchange membrane electrolysis, outperforming previous approaches by up to 12 percentage points. The system consists of a four-junction CPV system driving two PEM cells in series and is seen as a promising future generation product for solar hydrogen production. A startup will be formed with partner Clearsun Energy to commercialize this technology and bring it closer to achieving competitive low-levelized costs.
