Nano self-cleaning protective agent applicable to photovoltaic power generation cell panels

Abstract

The invention relates to a nano self-cleaning protective agent applicable to photovoltaic power generation cell panels. The nano self-cleaning protective agent is prepared from, by weight, 6-8% of long-chain organic siloxane, 0.1-1% of organic acid or inorganic acid, 6-10% of inorganic materials, 0.1-1% of a dispersing agent, 65-75% of an organic solvent and 10-15% of water, wherein the long-chain organic siloxane refers to CnH2n+1Si(OCmH2m+1)3, n is 25-30, and m is equal to 5; the long-chain organic siloxane also refers to CBr3CBr2(CH2)t(CH2)nSi(OCmH2m+1)3, t is equal to 7, n is 10-15, and m is equal to 5. The nano self-cleaning protective agent has advantages that a specific artificial bio-simulated structure is achieved, manual cleaning cost is reduced greatly, and hydrophobicity, hardness and surface smoothness of the nano self-cleaning protective agent are improved; since an anti-fouling mechanism of the nano self-cleaning protective agent takes advantages of low surface energy of a coating and a water contact angle is a critical parameter for measuring the surface energy of the coating, the larger the water contact angle, the lower the surface energy of the coating, the better the hydrophobicity and the antifouling performance.

Description

technical field [0001] The invention is applicable to the field of glass processing, and in particular relates to a nanometer self-cleaning protective agent for photovoltaic power generation battery panels. Background technique [0002] Photovoltaic power generation system is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. The key component of this technology is a solar cell. After the solar cells are connected in series, they can be packaged and protected to form a large-area solar cell module, and then cooperate with power controllers and other components to form a photovoltaic power generation system device. The advantage of the photovoltaic power generation system is that it is less restricted by the region, because the sun shines on the earth; the photovoltaic system also has the advantages of safety and reliability, no noise, low pollution, no need to consume fuel and erect transmiss...

AI Technical Summary

Problems solved by technology

[0003] At present, the solar cells in actual use basically do not use similar self-cleaning technology. The main reason is that on the one hand, users have not paid enough attention to it. Glossy, super stain-resistant surfaces are extremely technically difficult, and it is impossible to achieve practical results with traditional or single technology

[0004] At present, the mainstream product of protective glass used in solar cells is low-iron toughened patterned glass (or called toughened suede glass), with a thickness of 3.2 mm. The contact angle of the glass surface is 50-90 degrees. This kind of surface is easy to adhere to dust, water vapor, oily pollutants, etc. in the air. If it is outdoors for a long time, its light transmission will inevitably be greatly reduced.
