Description

Technical Field

[0001] The invention relates to the technical field of solar cells, in particular to a processing method of a solar cell component using a composite material. Background Art

[0002] As the global energy crisis intensifies and environmental pollution becomes increasingly serious, the development and utilization of solar energy as a clean and renewable energy source has attracted more and more attention from the world. As the core component of the solar power system, solar panels are responsible for the important task of efficiently converting solar energy into electrical energy. Their performance and life are directly related to the efficiency and reliability of the entire system.

[0003] In the traditional production process of ribbon-type solar cell modules, the welding of the ribbon usually needs to be performed at a higher temperature. However, during high-temperature welding, the high temperature environment may cause the electrode points on the battery to fall off, resulting in poor welding. In addition, after the welding cools down, the battery cell may warp due to the effect of thermal stress, which seriously affects the production yield and the long-term stability of the module. At the same time, during the packaging process of solar cells, plates and packaging materials are set on the outside, which are generally connected to the power generation unit in turn, and the processing steps are cumbersome.

[0004] At the same time, for the production process using conductive backplane as interconnect material, the pre-patterned conductive material is adhered to the adhesive film. During this process, the material may shrink to varying degrees before and after processing and under different room temperature conditions. This shrinkage may cause the position of the pattern to shift, which in turn affects the precise alignment of the cell electrode point and the conductive pattern, increasing the defect rate in the production process. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a method for processing solar cell modules using composite materials, which solves the problem that the electrode points on the battery may fall off due to high temperature, resulting in poor welding. In addition, after the welding is cooled, the battery sheet may be warped due to the effect of thermal stress, which seriously affects the production yield and the long-term stability of the module. At the same time, during the packaging process of solar cells, plates and packaging materials are set on the outside, which are generally connected to the power generation unit in turn, resulting in cumbersome processing steps.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for processing a solar cell module using a composite material, the processing method comprising the following steps:

[0007] Step 1: Lay the composite material of the front plate and the front package;

[0008] Step 2: A plurality of positive and negative electrode points are arranged on the power generation unit, and an insulating structure layer is arranged on the positive and negative grid lines; a conductive material is arranged on the battery cell of the power generation unit;

[0009] Step 3: Use a robot to lay the power generation units in sequence at the designated positions of the front packaging material;

[0010] Step 4: Use a robot to lay the conductive tape on the electrode points of the power generation unit in sequence, so that the conductive material is between the power generation unit and the conductive tape to form an effective contact;

[0011] Step 5: The laminated material is baked and heated, and the conductive material is partially solidified after being heated, so that a pre-bonding is formed between the power generation unit and the conductive tape;

[0012] Step 6: After laying the back packaging material and backboard material, lamination is performed.

[0013] Preferably, the front panel material can be glass or a transparent front panel, and the front packaging material can be but is not limited to EVA, EPE, POE, PVB, or an inorganic silica gel material, and the two are compounded together.

[0014] Preferably, the conductive material is arranged on the battery cell of the power generation unit by dispensing or printing.

[0015] Preferably, the conductive material can be, but is not limited to, tin-bismuth alloy paste, polymer conductive paste, or silver paste.

[0016] Preferably, the conductive tape may have a width of 0.5 to 20 mm.

[0017] Preferably, the conductive tape material can be but is not limited to single substances such as copper, aluminum, silver, gold, nickel, tungsten, or alloys of two or more thereof.

[0018] Preferably, the laminated material of the conductive material, the power generation unit and the conductive tape is baked and heated by infrared or baking lamp.

[0019] Preferably, the heating temperature of the laminated material of the conductive material, the power generation unit and the conductive tape does not exceed 150°C.

[0020] Preferably, the back panel material can be glass or a transparent front panel, and the back packaging material can be but is not limited to EVA, EPE, POE, PVB, or an inorganic silica gel material.

[0021] Preferably, the back panel material and the back side packaging material can be composited.

[0022] The present invention discloses a method for processing a solar cell assembly using a composite material, which has the following beneficial effects:

[0023] 1. The processing method of solar cell modules using composite materials, using composite materials for front panel and front packaging and composite materials for back panel and back packaging, can ensure the packaging steps of photovoltaic modules, improve quality, and reduce performance degradation caused by poor packaging. The selection and composite processing of composite materials can ensure good contact between power generation units and packaging materials, reduce current loss during transmission, and thus improve the power generation efficiency of solar cell modules.

[0024] 2. In the processing method of solar cell modules using composite materials, all processes before lamination and working conditions are carried out at low temperatures, which can effectively avoid the influence of high-temperature welding on the electrode points of the power generation unit, solve the problem of electrode point falling off, and greatly improve the production yield; the conductive tape is made in a real-time patch manner, and the ultra-high-precision mechanical laying equipment can accurately attach the conductive tape to the specified position one by one to ensure processing accuracy; the overall product has a two-dimensional packaging structure, and through the low-temperature packaging process, there is no thermal stress between the conductive tape and the battery cell of the power generation unit, which further reduces the risk of desoldering and hidden cracks, and the product reliability is better.

[0025] 3. In the processing method of solar cell modules using composite materials, the front and back panels are usually made of glass or transparent front panels. These materials, due to their good light transmittance and mechanical strength, become the first barrier to protect the power generation unit from damage by the external environment. Glass or transparent front panels can effectively prevent the erosion of the power generation unit by harmful factors such as wind, sand, rain, snow, and ultraviolet rays, thereby extending the service life of photovoltaic modules. The front and back packaging materials such as EVA, EPE, POE, PVB or inorganic silica gel not only have good adhesion and can be tightly adhered between the power generation unit and the front panel to prevent the entry of impurities such as moisture and dust, but also have good sealing properties, can isolate the air, and prevent the power generation unit from aging due to oxidation.
