Problems solved by technology

[0004] Black components have a strong absorption of infrared light, resulting in a large temperature rise of the components, which is 2-8°C higher than that of white or colorless components, and the power of the components is 1.5%-5% lower than that of ordinary components.
When the photovoltaic EVA film of the prior art encapsulates black components, due to the low infrared reflectivity of the photovoltaic EVA film, the high power consumption and temperature rise caused by the black components cannot be effectively reduced, making the components encapsulated by the EVA film whiter Or colorless components consume much more power, and the temperature rise is more obvious

Abstract

The invention discloses a black infrared reflection type photovoltaic EVA (Ethylene Vinyl Acetate) adhesive film. The photovoltaic EVA adhesive film comprises EVA resin as well as the following raw materials counted by the mass of the EVA resin: 0.1-2% of a cross-linking agent, 0.1-2% of an assistant crosslinker and 0.05-0.5% of an infrared reflection pigment. According to the photovoltaic EVA adhesive film, the infrared reflection pigment is added in the EVA resin, is black and has high infrared reflectivity, so that the prepared EVA adhesive film has good infrared reflection performance; by packaging a photovoltaic assembly by virtue of the photovoltaic EVA adhesive film, the power loss and temperature rise of the packaging assembly can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic EVA adhesive films, in particular to a black infrared reflective photovoltaic EVA adhesive film. Background technique [0002] Photovoltaic industry is an industry with rapid technological update and development. At present, the photovoltaic industry is developing towards diversification. The research and development of various functional components with high reliability, high power, low energy consumption and low cost has become a direction of photovoltaic module development. On the basis of the production of traditional components in ordinary EVA packaging, various photovoltaic manufacturers are also developing new functional components, such as double-sided glass components, anti-glare components, heat dissipation components, and black components. [0003] Photovoltaic EVA film is usually colorless, transparent or white material. White EVA film is usually used on the lower layer of the mo...
