Abstract

The invention provides a co-extrusion adhesive film, a solar cell module and double-layer glass. The co-extrusion adhesive film comprises at least two adhesive film layers; raw materials for forming each adhesive film layer comprise a first component and a second component, wherein each first component is 1-100 parts of first matrix resin grafted with an electron withdrawing group, and second components respectively and independently contain 0.01-25 parts of a water producing agent and / or 0.01-2.5 parts of a catalyst, and the second components are not water producing agents or catalysts at thesame time; and the first matrix resin and the water producing agents can undergo cross-linking reactions, and the catalysts can catalyze the cross-linking reactions. When the co-extrusion adhesive film is used as a raw material for preparing the solar cell module, the photoelectric conversion efficiency of the solar cell module can be greatly improved; and cost is low, process is simple, and industrial popularization is convenient.

Description

technical field [0001] The invention relates to the field of solar cell manufacturing, in particular to a co-extrusion adhesive film, a solar cell module and double-layer glass. Background technique [0002] In solar modules, the photovoltaic co-extrusion film is the only "barrier" between the silicon wafer and the outer glass. In order to ensure the high photoelectric conversion efficiency of the solar module, the co-extrusion film needs to have excellent barrier properties, Creep properties, etc., and the above properties of photovoltaic co-extrusion film are closely related to its cross-linking degree. In addition, in order to avoid glue overflow during the lamination process, it is necessary to reduce the fluidity of the film during lamination. Generally, the fluidity of the film is controlled by adjusting the pre-crosslinking degree of the film. [0003] At present, film crosslinking generally adopts the following methods: chemical crosslinking, radiation crosslinking,...
