Abstract

The invention belongs to the technical field of photovoltaic materials and provides a coating solution for a photovoltaic module, a preparation method of the coating solution and the photovoltaic module. The coating liquid for the photovoltaic module comprises alcohol solvent, silicon dioxide nanoparticles and vanadium dioxide-silicon dioxide nanoparticles, wherein the silicon dioxide nanoparticles and the vanadium dioxide-silicon dioxide nanoparticles are dispersed in the alcohol solvent, the vanadium dioxide and silicon dioxide nanoparticles are of a core-shell structure with an inner core coated with a shell layer, the inner core is vanadium dioxide, the shell layer is a silicon dioxide layer, and silicon dioxide dendrites are arranged on a surface of the silicon dioxide layer. When thecoating liquid is used for coating a photovoltaic module, the photovoltaic module can automatically adjust the transmittance of near-infrared light in a high-low temperature environment, and has an autonomous temperature regulation and control characteristic, and meanwhile, the photovoltaic module has excellent waterproof performance, and the service life of the photovoltaic module can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic materials, and in particular relates to a coating liquid for photovoltaic components, a preparation method thereof and a photovoltaic component. Background technique [0002] With the continuous improvement of solar cell efficiency, the photoelectric conversion efficiency of a single solar cell has approached the theoretical efficiency. It is difficult to greatly improve the photoelectric conversion efficiency through cell research and development and process improvement. At the same time, the design of photovoltaic modules has become a One of the key factors restricting the development of solar cells. How to reduce the power attenuation of photovoltaic modules in applications has increasingly become a problem of high industrial value. [0003] In the photovoltaic module system, on the one hand, due to the radiation of sunlight, energy is absorbed by the photovoltaic module, which leads to a...
