Problems solved by technology

[0003] In addition, the solar cell modules processed by the above-mentioned process will be limited by the lamination shape and size of the laminator, so the processed solar modules are basically They are all planar photovoltaic components, but cannot process curved solar cell components; and there is also a limit to the size of the processed solar components, therefore, this process cannot process large-area solar cell components

Embodiment 1

[0053] Such as figure 2 , 3 As shown, the solar cell assembly produced in this embodiment is a planar solar cell assembly.

[0054] Such as figure 1 As shown, the specific steps of the manufacturing method of the planar solar cell module are as follows:

[0055] 1) After the photovoltaic glass 1 is cleaned, the back plate 5, a plurality of solar cells 6 connected in series, and the photovoltaic glass 1 are stacked to assemble a stacked assembly, wherein the solar cells 6 are in the Between the back plate 5 and the photovoltaic glass 1 in the stacked assembly, that is, in the internal space of the stacked assembly;

[0056] 2) A sealing strip 4 is provided at the edge of the internal space of the stacked assembly to seal the internal space, and a glue inlet 2 and a glue outlet 3 are provided on the sealing strip 4;

[0057] 3) Connect the glue outlet 3 to an external vacuum pump, seal the glue inlet 2 with a rubber clip, and turn on the vacuum pump connected to the glue o...

Embodiment 2

[0068] Such as Figure 4 , 5 As shown, the solar cell assembly produced in this embodiment is a curved solar cell assembly.

[0069] The difference between the manufacturing method of the solar cell module in this embodiment and the manufacturing method in Embodiment 1 is: in step 2), after sealing the inner space of the stacked module with the sealing tape 4, and then sealing the The two ends of the above-mentioned stacked assembly are respectively fixed on the slots 8 of the manufacturing tool, and then the soft film 9 is installed on the back plate 5 . The soft film 9 forms a sealed space in the curved solar cell assembly, and can adapt to the shape of the curved surface assembly, allowing optical glue to be injected to form the curved surface solar assembly.

[0070] Since the shape of the solar cell module in this embodiment is a curved surface, it cannot be directly placed on a horizontal surface for processing, so it is placed on the tooling slot 8 to facilitate subse...

Abstract

The invention provides a manufacturing method of a solar battery module. The method comprises the following steps: stacking a backboard, a solar battery sheet and photovoltaic glass together to form a stack assembly; (2) sealing internal space of the stack assembly; (3) carrying out vacuum-pumping on the sealed internal space of the stack assembly; (4) injecting optical cement into the internal space of the stack assembly after vacuum-pumping processing; and (5) after filling out the internal space of the stack assembly with the optical cement, sealing the internal space. Correspondingly, the invention provides a solar battery module prepared by employing the above method. The manufacturing method of the invention is simple in technology, operation time can be substantially shortened, and product yield is high.

Description

technical field [0001] The invention relates to a manufacturing method of a solar battery module and a solar battery module made by the manufacturing method. Background technique [0002] At present, solar cell modules are mostly made of thermal lamination process through a laminator: the heat-encapsulating material EVA (ethylene-vinyl acetate copolymer, that is, ethylene-vinyl acetate copolymer) is melted under vacuum conditions and then wrapped. Around the solar cells, the purpose of protecting the solar cells from external damage is achieved. In this process, the laminator needs to be evacuated, and after heating and cooling processes, the processing time of a single solar module is as long as ten minutes, and the operation time is long and the efficiency is low. Moreover, since the existing thermal lamination process requires the use of professional processing equipment and molds, there are still problems such as expensive equipment and complicated processes in the pro...
