FIELD: power engineering.
SUBSTANCE: invention relates to devices for converting solar energy into electrical energy. Photoelectrochemical cell comprises an electroactive electrode and a photoactive electrode placed in a common housing, design of which includes graphite plates equipped with unions for supply of electrolyte and current collectors, separated by a proton-conducting polymer membrane, aluminium pressure plates with a window for light transmission to the photoactive electrode and without a window. Aluminium pressure plates and graphite plates are insulated with gaskets. Electroactive and photoactive electrodes are placed between graphite plates and said gaskets.
EFFECT: photoelectrochemical cell combines the functions of a photoelectric cell and a fuel cell intended for production of hydrogen under action of solar radiation in electrolytic cell mode and generation of electric current in the absence of solar radiation.
