Project overview

FotoH2 shall develop a highly efficient tandem photoelectrolysis cell for solar H2 production, based on durable and cost-effective advanced materials and interfaces. Applying the consortium partners’ experience with innovative solar technologies, the main vision of FotoH2 is the prototyping and validation of a mass-deployable solar H2 production technology, in the form of easily integrable flat panels. The input H2O and output H2 are carried by tubing at the two edges of the panels, comprising a self-powered flow- through system which can be simply connected to a water source. The semiconductor tandem architecture is expected to yield higher efficiency and allow more flexible deployment than externally biased architectures The validation of the technology will be done on a 1 m2-scale.
