Fraunhofer ISE achieves 31.3% solar-to-hydrogen efficiency with integrated concentrating solar module

Summary

Researchers at Fraunhofer ISE have achieved a record 31.3% solar-to-hydrogen efficiency using a new module that directly couples concentrating solar cells with PEM electrolysis. The integrated design eliminates the need for intermediate power conversion, enabling direct water splitting from solar-generated electricity. The breakthrough demonstrates highly efficient direct hydrogen production from sunlight.
