A cell includes a transparent covering element arranged at a top side of the cell, an interior arranged below the covering element, the interior being partly filled with an electrolyte, and a semiconductor absorber arranged in or at the electrolyte. Furthermore, the cell includes one or more counterelectrodes arranged above the semiconductor absorber in the electrolyte and electrically connected to a back electrode arranged at a rear side of the semiconductor absorber facing away from the covering element, and one or more membrane enclosures, wherein a counterelectrode in each case extends within a membrane enclosure. One or more channel spaces are formed between an electrolyte surface and an underside of the covering element, the one or more channel spaces extending along one or more partial regions of the underside of the covering element and being usable for guiding away a first gas formed in the interior of the cell.
