Problems solved by technology

However, due to the characteristics of fluorine materials, they have high surface energy, hydrophobic surface and poor bonding performance.
The bonding performance of the backplane and EVA is reduced, which makes the bonding process of the backplane and EVA complicated.

Abstract

The invention discloses a solar cell base film made from norbornene copolymer, which is characterized in that the base film is a single-layer structure which is made from norbornene copolymer, PC (polycarbonate), EVA (ethylene vinyl acetate) and fillings, or norbornene copolymer, POE (polyolefin elastomer), EVA and fillings, or norbornene copolymer, PP (polypropylene), EVA and fillings, or norbornene copolymer, eutectics of PET (polyethylene terephthalate) and fillings; and the base film of the single-layer structure is obtained by processing by the melt extrusion technology. The solar cell base film made from norbornene copolymer disclosed by the invention has the characteristics of resistance to heat and humidity, ageing, tear and hydrolysis, high barrier property to water vapor, high insulating property, high strength, stable size and easiness in processing and shaping, is good for protecting a solar cell module, and is capable of prolonging the service life of the solar cell.

Description

technical field [0001] The invention relates to the field of solar cell base films, in particular to a norbornene copolymer solar cell base film. At the same time, it also relates to a processing technology of the solar battery base film. Background technique [0002] The solar panel is usually a laminated structure, which is usually made of several polymer materials. However, the coating surface of the back film of the solar cell made by this technology has waves, which makes the coatings not tight and the device is durable. Sex is not high. Moreover, after the back film is completed, it needs to be packaged with EVA film, which increases the price process of the solar cell module, and the sealing performance is not high. For example, the Chinese patent application number is CN201010270646.3, the publication date is April 6, 2011, and the invention patent application with publication number CN102005491A discloses a high-fluorine alloy coated solar photovoltaic cell back f...
