Underwater communication detector of water electrolyte and manufacturing method thereof

The invention relates to the technical field of semiconductor devices and manufacturing of the semiconductor devices, in particular to an underwater communication detector of water electrolyte and a manufacturing method of the underwater communication detector. The light response network layer is formed on the main detection polar plate; the photoresponse network layer is a one-dimensional nano network composed of composite nanowires, and the composite nanowires have the function of absorbing external photons to generate photo-induced electrons and photo-induced holes; and the auxiliary polar plate is electrically connected with the main detection polar plate through an external circuit. According to the detector provided by the invention, a one-dimensional photoresponse network layer is formed by the composite nanowires with a photon absorption function, a larger solid-liquid reaction interface can be provided, a one-dimensional transfer channel is provided for photo-induced electron transfer, self power sup
