Abstract

The invention discloses a photovoltaic coating for improving solar energy conversion and a preparation method thereof. The coating is prepared from acrylic modified silicone resin, silica sol, polyethylene terephthalate, graphene, butyl titanate , nano titanium dioxide, nano silicon dioxide, single crystal silicon, photopolymerization catalyst, polyisocyanate, modified attapulgite clay, metal nanoparticles and antifoaming agent. The above components are reacted and uniformly mixed according to a certain ratio, and the photovoltaic coating is obtained. The coating not only has better waterproofperformance, aging resistance and electrical conductivity, but also can effectively improve the conversion of solar energy into electric energy, and provides a good application prospect for the development of solar photovoltaic materials.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic materials, in particular to a photovoltaic coating for improving solar energy conversion and a preparation method. Background technique [0002] Solar energy technology will become one of the green energy technologies in the future. Solar energy or photovoltaic (PV) is widely used in China, especially in recent years, as the production cost of polysilicon, the raw material of solar cells, has been greatly reduced, and the production technology of solar cells has been perfected day by day. The output of solar cells in the world has increased very fast in 2010, which can be said to be an extremely promising industry, and the application of photovoltaic coatings in solar photovoltaic cells has gradually been discovered. [0003] Today, it is difficult to imagine a modern life without coatings, both in industry and in daily life. Most of the existing coatings are used in the field of const...
