摘要
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 is formed with the ion exchange layer 61 in contact with the electrode structure of the front electrode 21 formed for conversion of the electrolyte 10 and/or with the electrode structure of the rear electrode 22.
