Abstract

The invention provides a preparation method of a photovoltaic device based on gradient silicon dioxide particles. The preparation method comprises the following steps: respectively dispersing silicondioxide particle powder with different sizes into a solvent to obtain silicon dioxide slurries; and then respectively coating a substrate with the silicon dioxide particle slurries with different sizes from bottom to top, and drying to obtain the photovoltaic device based on the gradient silicon dioxide coating, wherein small-size nanoparticles are arranged at the bottom, and the sizes of the nanoparticles are gradually increased from bottom to top. According to the invention, the photovoltaic device prepared by the method provided by the invention can spontaneously generate electric energy byvirtue of the capillary action of the silicon dioxide coating and water evaporation, does not need additional energy input, is highly spontaneous in power generation mode, is less limited by the environment, has high energy output, can be maintained for a long time, and is suitable for various application scenes.

Description

technical field [0001] The invention relates to the field of preparation of water evaporation and power generation devices, in particular to a preparation method of a hydrovolt device based on gradient silicon dioxide particles. Background technique [0002] Hydrovoltaic power generation devices are expected to develop into very compact clean energy supply and intelligent systems. It can be combined with wind energy, solar energy, waste heat, etc. to significantly increase the amount of evaporative power generation, and has a larger development space than photovoltaic technology in theory. Water covers about 71% of the Earth's surface and accounts for about 70% of the human body by weight. Water is closely related to energy and maintains the energy cycle of the earth system, the temperature balance of organisms, and is a natural energy absorber, energy storage, transducer and energy transmitter. Nearly 70% of the energy from solar radiation reaching the surface is absorbed...
