Problems solved by technology
[0003] In the field of photovoltaic power generation, the encapsulation film is a key component. The encapsulation film is an organic material. The encapsulation film for photovoltaic modules is packaged in rolls before production is completed and used. Layers and layers are used in environments with high humidity or high temperature. It is easy to stick together, which affects the use of the encapsulation film and shortens the shelf life of the encapsulation film

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the drawings and embodiments.
[0031] Reference figure 1 As shown, a packaging adhesive film provided by an embodiment of the present invention includes: an adhesive film main body 1 and two thickened parts 2. The thickened parts 2 are provided on both sides of the length of the adhesive film main body 1, and the thickened The length of the part 2 is the same as the length of the main body of the adhesive film. Wherein, the thickness of the thickened portion 2 is greater than the thickness of the adhesive film main body 1. When the packaging adhesive film of this structure is packaged in a roll, the contact area between the layers is reduced, and adhesion and pre-crosslinking are avoided before the packaging adhesive film is produced and used.
[0032] Such as image 3 As shown, in this embodiment, the adhesive film main body 1 and the thickened portion 2 are integrally formed to form an integral adh...

Abstract
A packaging adhesive film and a photovoltaic module are provided. The packaging adhesive film comprises an adhesive film body. Thickened portions are arranged on the two sides along the length direction of the adhesive film body, and the thickness of the thickened portions is greater than the thickness of the adhesive film body. The bonding problem of packaging adhesive films after rolling is solved. The thickened portions are provided with grooves, which are conducive to the overflow of gas in laminated parts during lamination. Moreover, the occurrence probability of defects such as bubbles and glue shortage in the production of photovoltaic modules is reduced.
Description
Technical field [0001] The invention relates to the field of photovoltaic power generation, and more specifically to a packaging glue film and a photovoltaic module adopting the packaging glue film. Background technique [0002] In today's society, traditional fossil energy is gradually depleted, and human development needs to find new alternative energy sources. In addition to global warming, major industrial countries in the world encourage the extensive development of clean energy in order to reduce carbon emissions. Photovoltaic power generation is not only pollution-free, but also inexhaustible. It is the mainstream of future energy use. According to the European Photovoltaic Industry Association (EPIA) forecast: in 2030, renewable energy will account for 30% of the total energy consumption, and photovoltaic power generation will account for more than 10% of the world's total electricity; in 2050, renewable energy will account for the total energy consumption. Above 50%, ph...
