Problems solved by technology

However, part of the replacement of POE with cheaper EVA in this invention is only to reduce the cost of the POE film, and the shortcomings of the POE film itself have not been improved, such as the disadvantage that the surface additives of the POE film are easy to precipitate
[0004] In addition, in the multi-layer adhesive film of the prior art, the substrate (except auxiliary) material used in each layer of adhesive film is a single material
In the actual production process of its products, the yield rate is low, and the leftover materials cannot be recycled

Abstract

The invention provides a photovoltaic module containing a multilayer packaging adhesive film and a preparation method thereof. The photovoltaic module containing the multilayer packaging adhesive filmcomprises a front plate, an upper layer adhesive film, a battery piece, a lower layer adhesive film and a rear plate which are sequentially arranged from top to bottom, at least one layer of the upper layer adhesive film and the lower layer adhesive film is the multilayer packaging adhesive films, and the multilayer packaging adhesive film comprises at least two layers of packaging adhesive films. The photovoltaic module containing the multilayer packaging adhesive film has excellent PID resistance, and can meet the requirements for the packaging adhesive films with different functions.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic components, and relates to a photovoltaic component containing a multi-layer encapsulation adhesive film and a preparation method thereof. Background technique [0002] Encapsulation materials play the role of bonding protection in modules. More and more cells are used in photovoltaic modules. The performance of various cells is different, and the requirements for encapsulation film are also different; for example, P-type cells require high resistance. Adhesive film with PID performance; Heterojunction cells with round ribbons need a non-slip adhesive film, CIGS cells are afraid of heat and need low-temperature lamination, etc. The requirements for the packaging film are getting higher and higher, and it is difficult for a single layer of film or a single material to meet the packaging requirements. There is an increasing demand for multi-layer adhesive films and adhesive films prepared by b...
