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 prod

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.
