In this embodiment, the photoelectrode of the photoelectrode module becomes an anode in water, the frame becomes a cathode in water, and a circuit is formed, and the reaction can be summarized as the following reaction equation:
2H 2 O→4e - +O2↑+4H + (anode, photoelectrode, holes move from cathode to anode)
