Abstract

An anti-reflective film for a solar cell panel comprises a hollow silicon dioxide layer, a composite silicon oxide layer, a waterproof layer and a wear-resistant layer. The anti-reflective film is prepared by sequentially spraying and drying the hollow silicon dioxide layer, the composite silicon oxide layer, the waterproof layer and the wear-resistant layer. The anti-reflective film has the beneficial effects that (1) the solar coating simultaneously has favorable heat absorption performance and waterproof performance, reflection of sunlight is effectively reduced, and the absorption rate ofthe solar cell panel on solar irradiation is improved; and (2) by Al<2>O<3>-Cu nanometer composite powder contained in the wear-resistant layer, the wear-resistant property and the hardness of the solar cell panel coating layer are finally improved.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to an anti-reflection film for a solar battery panel. Background technique [0002] Anti-reflection coating, also known as anti-reflection coating, its main function is to reduce or eliminate the reflected light from optical surfaces such as lenses, prisms, and flat mirrors, thereby increasing the light transmission of these components and reducing or eliminating stray light in the system. [0003] The simplest anti-reflection coating is a single-layer coating, which is a thin film with a low refractive index coated on the optical surface of an optical component. If the optical thickness of the film layer is a quarter of a certain wavelength, the optical path difference between two adjacent beams of light is exactly π, that is, the vibration direction is opposite, and the result of superposition reduces the reflected light of this wavelength on the optical surface. When the refractive i...
