The photoelectrochemical cell: Sunlight generates a photovoltage in the catalyst-coated solar cell (right), which splits water molecules. Hydrogen is produced at the left electrode, oxygen at the ...

Schematic diagram of PV-PEC water splitting based on BSs. (a) Spectrum reaching the BS1; (b) spectrum reaching the TiO2; (c) spectrum reaching the BiVO4; (d) spectrum reaching the PV cell.

The solution, which is at the proof of concept stage, comes in the form of a pyroelectrochemical cell (PEC). Developed by associate professors of mechanical engineering Roseanne Warren and Shad ...
