The aim of this project is the fabrication of a medium-sized demonstrator cell with an active electrode area of 40cm 2, achieving overall water splitting at a competitive efficiency (at least 10% solar-to-hydrogen efficiency) by improving the photoanode, the photocathode and the device architecture (tandem device). In a tandem device the anode and the cathode are photoelectrochemically active. This opens the door to the fabrication of larger scale demonstrators and is a significant step towards an industrial use of the PEC-cell for hydrogen production. [read on]
