With the development of solar cell technology, more and more solar cell modules are applied to various scenes, such as solar power generation backpacks, solar power generation mobile power sources, automobile skylights, and the like. As the number of applications of the solar cell module increases, the appearance of the solar cell module is required to be more, and the solar cell module is required to form a curved surface structure.

The existing solar cell module structure includes: the solar cell comprises a front plate, an adhesive film, a solar chip, an adhesive film and a back plate. In the prior art, most of solar cell modules with curved surface structures are directly formed by one-step lamination, namely, multiple layers of packaging materials are applied together and placed on a mold, and then are formed by one-step lamination, and the physical reaction and bonding of the multiple layers of packaging materials are realized in one-step lamination.

However, according to the scheme, the adhesive film needs to be melted during direct lamination, and when the solar cell module with the curved surface structure is prepared, the surface of the mold is set to be the curved surface, so that the adhesive film flows under the action of gravity, extrusion force and the like after being melted, the adhesive film is further unevenly distributed and even overflows, and the yield is low.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

a method of laminating a solar cell module, comprising the steps of:

fixing the planar solar cell module on a mold, setting the bearing surface of the mold into a curved surface, and then sequentially carrying out preheating operation and heating laminating operation on the planar solar cell module to obtain the solar cell module with the curved surface structure, wherein the bending degree of the bearing surface of the mold is consistent.

Secondly, because the surface of the molded planar solar cell module is flat, and the surface of the mold has curvature, if the planar solar cell module is directly laminated for the second time, the planar solar cell module is unevenly stressed in the laminating process, and the adhesive film can be extruded or the planar solar cell module is fractured due to sudden stress, and the planar solar cell module has a process of softening in advance by setting a preheating step, so that the occurrence of the condition of extruding or fracturing the adhesive film is avoided.
