Photovoltaic water electrolysis integrated hydrogen production device

The invention discloses a photovoltaic water electrolysis integrated hydrogen production device which comprises a reaction box, a plurality of bolts evenly distributed on the side wall of the reaction box at equal intervals, a sealing cover hinged to the side end of the reaction box and a sealing gasket arranged at the lower end of the sealing cover. The single-junction perovskite solar cell is fixedly arranged outside the reaction box; the electrocatalyst and the carrier material of the electrocatalyst are fixedly arranged in the cathode chamber and the anode chamber; the wire connecting holes are formed in the top of the cathode chamber and the top of the anode chamber; according to the integrated hydrogen production device, an integrated direct coupling mode is adopted, the perovskite solar cell is connected with a water electrolysis device, meanwhile, the perovskite cell is combined with a catalyst, the integrated hydrogen production device is manufactured, and hydrogen can be more conveniently produced.
