The electrode potential is P-type.A negative potential appears in a semiconductor electrode, and a base potential appears in a metal electrode, and an electromotive force is generated between the electrodes.In the process of converting light energy into electrical energy, an aqueous solution as an electrolyte is decomposed, resulting in a P-type electrode potential. At the semiconductor electrode, hydrogen is generated through a cathode reaction, while at the metal electrode, oxygen is generated through an anode reaction.
