Technical Field

The invention belongs to the technical field of new energy, and particularly relates to a device for realizing sustainable electricity generation by utilizing a photovoltaic effect of a nano structure.

Background

With the exhaustion of fossil energy and the resulting environmental problems, governments around the world have come to believe that renewable energy is an important technology for reducing the environmental problems associated with energy, particularly carbon dioxide emissions. Renewable energy accounts for less than 3% of the global electric power and 2% of primary energy. They are undoubtedly potentially very large in scale and can in principle make a very large contribution to the world's energy demand.

The earth's surface is 75% covered by seawater, which is the origin of life and also an essential resource for life survival. Water has an important role in maintaining energy circulation in the earth's energy system. Water energy is a clean and pollution-free renewable energy source, and water motion such as gravitational potential energy, tide rise and fall, waves and swell and the like of water can be used for generating electricity. Since the nineteenth century, people find that water can generate flowing potential when passing through a capillary glass tube, the flowing potential is called as electrokinetic effect, the scientific principle of the electrokinetic effect is based on the combination of thermodynamics and electrostatics, and an electric signal is generated by an electric double layer formed on a solid-liquid interface through shearing force. This patent is through utilizing cheap materials such as timber and carbon black, can continuously produce the electric energy to friendly to the environment, easy operation, low cost.
