Abstract

The invention discloses a method for preparing photovoltaic glass with an integrated encapsulation adhesive film, comprising the following steps: selecting photovoltaic glass, laying an encapsulation adhesive film raw material on the photovoltaic glass, setting an anti-adhesive layer on the encapsulation adhesive film raw material, Then use a flat vulcanizer to press at a preset temperature and pressure for a preset time and then remove the anti-adhesive layer to obtain an integrated packaged thin-film photovoltaic glass. The method combines the photovoltaic glass and the encapsulation film, simplifies the material preparation and lamination process, reduces the production cycle of the crystalline silicon solar cell module, especially the production of the double glass module, and improves the production efficiency. The invention also discloses a preparation device for the integrated encapsulation adhesive film photovoltaic glass.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic modules, and in particular relates to a method and device for preparing photovoltaic glass with an integrated packaging adhesive film. Background technique [0002] At present, the preparation process of crystalline silicon solar cell modules is basically divided into cell string welding, BOM (bill of materials, bill of materials) material preparation, lamination, EL (electro luminescence, electroluminescence) inspection, lamination, framing and test packaging ;In the process of BOM preparation and lamination, since the current encapsulation film is basically coil packaging, it is necessary to cut the encapsulation film into sheets according to the size of the component using a cutting device for the subsequent lamination process. The layering process needs to place the glass on the bottom layer first, and spread the encapsulation film on the glass according to the specifications before perfo...
