Problems solved by technology

In order to ensure reliable welding between the ribbon and the cell and to prevent corrosion of the ribbon, the surface of the ribbon is coated with a tin layer. Therefore, there will be flux residues on the ribbon. When the photovoltaic module is packaged in EVA, these flux residues Will be in direct contact with EVA, and a slow chemical reaction will occur, resulting in air bubbles, resulting in a decline in the quality of the entire photovoltaic module

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] In order to achieve the purpose of the present invention, as figure 1 As shown, a film for photovoltaic modules includes an adhesive layer 2 and a PET layer 1 from bottom to top. Area.

[0026] Utilize the film of the present invention to cover the welding strip, and then carry out EVA packaging, because the PET layer plays an isolation role, the flux residue on the welding strip will not directly contact with the package EVA, completely eliminating the che...

Abstract

The invention provides a film used for a photovoltaic module, the photovoltaic module and a preparation method. The film used for the photovoltaic module comprises an adhesive layer and a PET layer from the bottom up in sequence; and the film is only used for covering a solder strip on the photovoltaic module and / or regions between battery pieces on the photovoltaic module. After the solder stripis covered with the film disclosed in the invention, EVA packaging is performed; and PET has an isolation effect, and soldering flux residue on the solder strip is not in direct contact with packagingEVA, so that the bad consequences caused by a chemical reaction between the two parties can be eliminated completely.

Description

technical field [0001] The invention relates to the field of photovoltaic cells, in particular to a film for photovoltaic components, a photovoltaic component and a preparation method. Background technique [0002] Photovoltaic ribbons are used in the connection between photovoltaic module cells, and play an important role in conducting electricity and collecting electricity. In order to ensure reliable welding between the ribbon and the cell and prevent corrosion of the ribbon, the surface of the ribbon is coated with a tin layer. Therefore, there will be flux residues on the ribbon. When the photovoltaic module is packaged in EVA, these flux residues It will be in direct contact with EVA, and a slow chemical reaction will occur, resulting in bubbles, resulting in a decline in the quality of the entire photovoltaic module. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to p...
