  • Photoelectrochemical cell, system and process for light-driven production of hydrogen and oxygen with a photoelectrochemical cell, and process for producing the photoelectrochemical cell
    Patent number: 10006130
    Abstract: The invention relates to a photoelectrochemical cell 100 for light-driven production of hydrogen and oxygen, especially from water or another electrolyte based on aqueous solution, having a photoelectric layer structure 1 and an electrochemical layer structure 2 in a layer construction 40, where—the photoelectric layer structure 1 for absorption of light 3 uninfluenced by the electrolyte 10 forms a front side 41 of the layer structure 40, and—the electrochemical layer structure 2, for accommodation of the electrolyte 10, forms a reverse side 42 of the layer construction 40, and—a conductive and corrosion-inhibiting coupling layer 13 forms electrical contact between the photoelectric layer structure 1 and the electrochemical layer structure 2 in the layer construction 40, where—the electrochemical layer structure 2 has an electrode structure of a front electrode 21 and an electrode structure of a rear electrode 22, between which is arranged an ion exchange layer 61 such that an integrated layer construction 40
