The invention relates to a novel low-cost two-port solar rechargeable device, comprising a Faraday junction photoelectrode and a counter electrode as two ports, with an electrolyte between the two ports, forming a two-port solar rechargeable device; the Faraday junction photoelectrode comprises Direct contact between two materials, a semiconductor and a farad body, the farad body is a conductor of electron-ion coupling. During light charging, the Faraday junction photoelectrode port and the counter electrode port are short-circuited; during dark state discharge, the Faraday junction photoelectrode port and the counter electrode port are connected with a load in the middle. The invention directly stores the solar energy in the device, and can directly release the electric energy to the external circuit, has simple operation and universality, and can effectively balance the day and night fluctuation of the solar energy. |
