OHPERA

Tandem PEC cell for efficient hydrogen production and industrial waste valorisation.

Hydrogen fuel generation from photoelectrochemical (PEC) water splitting is one of the most promising forms of energy production. The EU-funded OHPERA project plans to develop a proof-of-concept tandem PEC cell to simultaneously achieve efficient solar-driven hydrogen production at the cathode and high added-value chemicals from industrial waste valorisation at the anode. Researchers will integrate highly efficient and stable photoelectrodes based on halide lead-free perovskite nanocrystals and tailored catalytic layers, avoiding the use of critical raw materials. Theoretical modelling both at the atomistic and device scales will aid in materials development and improve understanding of the physical mechanisms that underlie their performance. All materials and components will be integrated into a proof-of-concept device.
