Abstract: A system which allows an aqueous electrolyte solution of a photoelectrode to prevent deterioration of photoactivity, and further more enables various types of photoelectric cells to be applied to a photoelectrochemical system by installing photoelectric cells separately from the aqueous electrolyte solution is provided. A system for the production of hydrogen through water electrolysis by light irradiation has a structure in which oxidation and reduction catalytic electrodes(2,3) and an ion membrane(4) between the oxidation and reduction catalytic electrodes are dipped into an aqueous electrolyte solution(5), and photoelectric cells(1) are electrically connected to the oxidation and reduction catalytic electrodes outside the aqueous electrolyte solution. The photoelectric cells are silicon semiconductor-based solar cells, dye-sensitized solar cells, chalcogen compound-based solar cells, oxide thin film-based solar cells, organic semiconductor-based solar cells, or combinations thereof.
