Embodiment Construction
[0049] In order to introduce the present invention more clearly, the structure of the photovoltaic module in the prior art is briefly introduced first. Such as figure 1 as shown, figure 1 It is a structural schematic diagram of a photovoltaic module in the prior art. The photovoltaic module mainly includes a module cover plate 101 , a first adhesive film layer 102 , a battery string 103 , a second adhesive film layer 104 and a module back plate 105 . After sunlight passes through the module cover plate 101 and the first adhesive film layer 102 in sequence, it enters the battery slices in the battery string 103 and generates current through the battery slices. Among the sunlight irradiated on the surface of the photovoltaic module, part of the sunlight is reflected by the module cover plate 101 and the first adhesive film layer 102, part of the sunlight is absorbed by the module cover plate 101 and the first adhesive film layer 102, and only part of the sunlight is Entering t...

The invention provides a photovoltaic module laminating method and a photovoltaic module. The photovoltaic module laminating method comprises the steps of sequentially laying a module cover plate, a battery string and a module back plate to obtain a module to be laminated, performing preset laminating operation on the module to be laminated, enabling the molten module cover plate to be in sealed connection with the battery string and the module back plate, and cooling the molten module cover plate to obtain a laminated module. The assembly cover plate and the battery string are directly connected in a sealed manner through the assembly cover plate, so that an adhesive film layer is prevented from being arranged between the assembly cover plate and the battery string. Compared with the prior art, in the power generation process of the photovoltaic module, absorption and reflection of sunlight by the adhesive film layer are avoided, and the light transmittance of the photovoltaic moduleis improved, so that the power generation efficiency of the photovoltaic module is improved.
Description
technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a method for laminating a photovoltaic module and a photovoltaic module. Background technique [0002] Photovoltaic power generation is a green energy technology that can reduce environmental pollution and protect the environment. Photovoltaic modules are one of the main tools for photovoltaic power generation. Improving the power generation efficiency of photovoltaic modules is conducive to the promotion and use of photovoltaic power generation technology. [0003] Light transmittance is one of the factors affecting the power generation efficiency of photovoltaic modules, and the light transmittance is mainly determined by the structure of photovoltaic modules. In the prior art, the light transmittance of the photovoltaic module is low, resulting in low power generation efficiency of the photovoltaic module. Contents of the invention [0004] The invention provid...
