Photovoltaic module processing method

Abstract

The invention discloses a photovoltaic module processing method. The method comprises the following steps: S1, manufacturing a semi-finished product; S2, manufacturing a surface layer; S3, conductingdie cutting on the incoming EVA roll material to form a middle EVA layer; S4, sequentially laminating the semi-finished product, the middle EVA layer and the surface layer; S5, transferring into a laminating machine for laminating; wherein the step S2 comprises the following sub-steps: step S21, slitting a surface layer raw material into sheets; S22, preparing customized printing ink; S23, printing the surface layer sheet; and S24, baking the printed surface layer sheet, and then obtaining the surface layer. The grid lines and the like are covered in a surface layer printing mode, a manual black tape pasting covering mode in a traditional process is replaced, the covering effect is stable, and manpower and black tape cost are reduced.

Description

technical field [0001] The invention relates to the field of photovoltaic component manufacturing, in particular to a photovoltaic component processing method. Background technique [0002] With the continuous improvement of people's living standards in recent years, green environmental protection has gradually become popular among the people. As a kind of green and renewable energy, civil solar products, on the one hand, bring high-quality product experience when everyone travels. On the other hand, its fashionable shape, diverse The appearance gives customers a sense of beauty. [0003] The appearance of solar energy products is very demanding in the field of civilian products. At present, the method of pasting black tape to cover the busbar, copper strip, and PCB rivet pad in the semi-finished stage has become the mainstream process in the industry.

Problems solved by technology

[0003] The appearance of solar energy products is very demanding in the field of civilian products. At present, the method of pasting black tape to cover the busbar, copper strip, and PCB rivet pad in the semi-finished stage has become the mainstream process in the industry. Among them, the stickiness of black tape and manual precision There are uncontrollable risks, high defects, and the high cost of black tape cutting, low efficiency of manual posting, black tape covering the cell leads to lower product output parameters and other factors have always been the technical and cost issues that have plagued various companies in the industry ;

[0004] In the field of ordinary single and polycrystalline solar cells in the photovoltaic industry, the busbar width of the existing cells is between 0.3mm and 2.0mm. In order to effectively reduce the appearance, the width of the black tape used in the industry is 1.5mm-4.5mm , taking the 156*156 five-line as an example, posting black tape leads to a reduction of product efficiency by about 10%, and the labor force for pasting black tape accounts for a large proportion of the total number of people on the semi-finished assembly line, which will undoubtedly greatly increase product costs and greatly reduce customer product experience;

[0005] In addition, in the field of Sunpower and LG solar cell patch in the photovoltaic industry, there are differences in the color of the rivet pad on the front of the single-sided copper clad laminate and the color of the cell, and the color of the PCB bottom plate (for example, the pad is silver-white, the silicon wafer is blue, and the PCB is black. ), resulting in low consistency of product appearance and unsatisfied customers' individual needs
