Über das Projekt
Ziel des Projekts H2Demo ist es, erstmals größere Demonstratoren für die direkte solare Wasserstoff-erzeugung herzustellen. Es werden in dem Projekt besonders vielversprechende Tandem-Absorber aus GaAsP/Si entwickelt, welche beste Chancen auf Wirtschaftlichkeit in Kombination mit hoher Effizienz und Skalierbarkeit aufweisen.
