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

Energy is often considered the cornerstone of economic growth, and the continuous growth of industrialization and global economy in countries around the world depends on abundant natural resources that can serve as energy sources for machines, greenhouses, and for powering billions of people. Although widespread use of energy has reduced global poverty by improving the living standard of billions of people, the problem of energy shortage has inhibited socioeconomic development. Energy poverty refers to individuals who cannot obtain modern energy services, and it is estimated that nearly forty hundred million people live under conditions of energy poverty.

Energy sources are vital to economic growth and social progress, and along with the development of economy and the continuous increase of energy requirements of human society, the lack of fossil energy and the pollution to the environment cause increasingly serious contradictions between energy supply, environmental protection and economic development. With the renewable utilization and no pollution of renewable energy, renewable energy will become an effective and realistic choice for guaranteeing future development of the world. Renewable energy generally refers to energy that does not pollute the environment and can be recycled in nature. International experts have now classified renewable energy sources into traditional renewable energy sources and new renewable energy sources. The former mainly includes large hydroelectric and biomass which are directly combusted; the latter mainly refers to small hydroelectric power, solar energy, wind energy, biomass energy, geothermal energy, ocean energy and the like. China is the largest developing country in the world, and the development of renewable energy sources is a necessary choice for the sustainable growth of economy, harmonious coexistence of people and the environment and sustainable development. However, since the 1960 s, the ability of renewable energy sources to replace fossil fuels was quite limited. The water contains enormous energy in various forms, and current research shows that the nanostructure material can interact with water to generate electric energy, and the basic principle is that water can ionize hydrogen ions and hydroxyl groups, and when the water is in contact with a charged solid, an electric double layer is formed at the interface. The electric double layer consists of a Stem layer anchored on the solid surface and a diffusion layer rich in counter-ions. The applied external force affects the diffusion layer to produce relative motion between the fluid and the solid, creating an electrokinetic effect that generates electrical energy. According to the invention, the sponge is used as a substrate, the carbon black is coated on the surface of the sponge, the hydro-voltaic effect can be utilized to generate electricity when water drops on the sponge, and the ferric chloride absorbs moisture in the air, so that the purpose of continuous electricity generation is realized.
