Problems solved by technology

In the technology mentioned above, when the photovoltaic cell panel is packaged, there are multiple bondings, and the bonding layer of the photovoltaic module packaged by bonding will be vaporized due to natural factors such as high temperature and high humidity during use. Cause water accumulation, bulging and other defects
For photovoltaic panels, extremely high insulation and waterproof effects are required during use, and a backplane structure that requires only one operation to achieve encapsulation has not been found in the prior art

Abstract

The invention belongs to the technical field of solar energy application, and in particular relates to the improvement and application of a weather-resistant solar cell backboard structure and a device for manufacturing the structure; Reciprocating motion, and then feed different layers of raw materials into the back plate forming cavity through different nozzles, so that the raw materials are cooled in the back plate forming cavity of the back plate forming cavity, and the raw materials during the cooling process are pressed by the conveying mechanism, and finally make The invention achieves the purpose of manufacturing a one-time molding cylindrical solar back panel.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and in particular relates to the improvement and application of a weather-resistant solar battery back plate structure and a device for manufacturing the structure. Background technique [0002] Since solar photovoltaic modules are installed outdoors, their working environment is relatively poor, and they are often exposed to wind, sun, and rain. Therefore, there are high requirements for the sealing and ultraviolet resistance of solar photovoltaic modules. The solar backsheet is a structural packaging material for solar cell components, which plays an important role in prolonging the service life of solar cells. It is an indispensable part of solar cell components and is also one of the important components of solar cell components. An excellent backsheet should have reliable insulation, water resistance, mechanical properties, UV aging resistance and humidity and heat aging res...
