Abstract

The invention discloses a nickel hydroxide- titanium dioxide-based photoluminescence energy storage method and a device thereof. In alkaline solution, a TiO2 porous membrane is sequentially prepared on the conductive surface of an ITO substrate; a double-film working electrode of a Ni(OH)2 membrane is deposited on the TiO2 porous membrane; a Pt counter electrode is arranged at one side of the double-film working electrode; and the two electrodes are connected through lead wires. In the ultra-violet Hv radiation, the potential difference of the two electrodes is used to push the electrons to transfer from an external circuit to the Pt counter electrode and react with the oxidation substances so as to be consumed, thereby reducing the composition between electrons and cavities, improving the oxidation efficiency of cavities which oxidate Ni (II) into Ni (III) and increasing the oxidation energy storage efficiency of the device.

Description

A nickel hydroxide-titanium dioxide based photoinduced energy storage method and device thereof technical field The invention relates to an energy storage method and device, in particular to a nickel hydroxide-titanium dioxide-based photoinduced energy storage method and device. Background technique The research and development of solar cells has become one of the research hotspots in the field of energy. However, solar photovoltaic cells can only output electrical energy under the condition of light, and cannot provide energy at night and cloudy days without sunlight, that is, its energy output has intermittent characteristics. This is in contradiction with the constant demand for electrical energy in most cases. One solution is to combine solar photovoltaic cells with energy storage batteries (such as lead-acid batteries, etc.), charge the batteries when there is sunlight, and output energy through battery discharge when there is no light. However, there are problems s...
