Problems solved by technology

[0003] In the stacked structure of the module in the prior art, the bonding strength and service life of the module are affected due to the low degree of cross-linking between EVA and the TPT back film; the light transmittance of ordinary tempered glass is not good, which restricts the photoelectric conversion rate of the module. Improvement; the process time from air pumping heat sealing to inflation taking out needs 1135 seconds, which is too long, which affects the production efficiency of the module; therefore, the solar cell module products in the prior art have short service life, low photoelectric conversion rate, and low production efficiency problems and deficiencies

Abstract

The invention discloses a laminated structure and laminating technology of a solar panel component. The laminated structure comprises coated and toughened glass (1), an EVA (2), a single crystalline silicon solar cell (3), an EVA (2) and a BBF back film (4) which constitute the five-layer structure. The laminating technology method comprises the following steps: exhausting and heat-conglutinating, laminating and cooling, aerating for decompression, and taking out the finished product. The invention uses the coated and toughened glass to replace the common toughened glass, uses the BBF back film which has high crosslinking degree to EVA to replace the TPT back film and adopts the corresponding technical scheme of the laminating technology so that the use of the coated and toughened glass can increase the photoelectric conversion efficiency of the component and the use of the BBF back film can increase the bonding strength so as to prolong the service life of the component, reduce the laminating and heat-conglutinating time, increase the production efficiency of the component and ensure to achieve the aim of increasing the photoelectric conversion efficiency, service life and production efficiency of the solar panel component.

Description

technical field [0001] The invention relates to the lamination structure and manufacturing process of solar photovoltaic cell panel components, specifically referring to the solar photovoltaic cell with the lamination structure of coated tempered glass, EVA fast-curing adhesive film, monocrystalline silicon cells, and BBF back film by adopting a heat-sealing lamination process. A stacked structure of a solar panel assembly and its lamination process in which the battery panel assembly is packaged and integrated. Background technique [0002] The laminated structure and its lamination process are the key factors that determine the electrical performance, mechanical strength and service life of solar cell modules. The lamination structure of the monocrystalline silicon solar cell module in the prior art is tempered glass, EVA film, monocrystalline silicon solar cells, and TPT back film; The laminated components are put into the laminator, and the air in the components is grad...
