In Short
About the project
The aim of the H2Demo project is to produce the first large-scale demonstrators for direct solar hydrogen production. This is the absorption of sunlight in a semiconductor structure that generates a sufficiently large photovoltage > 1.6 volts to decompose water directly into hydrogen and oxygen. In the project, particularly promising tandem absorbers made of GaAsP/Si are being developed, which have the best chances of economic viability in combination with high efficiency and scalability.
