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, wherein the raw materials for forming each adhesive film layer comprise a first component and a second component in parts by weight, the first component is 1-100 parts of first matrix resin grafted with an electron-withdrawing group, the second component independently contains 0.01-25 parts of water producing agent and/or 0.01-2.5 parts of catalyst, each second component is not a water producing agent and is not a catalyst at the same time, the first matrix resin and the water producing agent can generate a crosslinking reaction, and the catalyst can catalyze the crosslinking reaction. When the co-extrusion adhesive film is used as a raw material to prepare the solar cell module, the photoelectric conversion efficiency of the solar cell module can be greatly improved, and the co-extrusion adhesive film is low in cost, simple in process and convenient for industrial popularization. |
