In general, the usage environment of solar photovoltaic panels is relatively harsh, and the national regulations stipulate that the design service life of photovoltaic power stations is 25 years. Therefore, the reliability of solar photovoltaic module packaging is particularly important.

Which links in the photovoltaic industry process will affect the final packaging effect?

It is obvious that in the midstream solar photovoltaic panel manufacturing process, the reliability of the back panel, the lamination process, and the overall photovoltaic module packaging process are all important factors affecting the reliability of solar photovoltaic panel packaging.

How to improve the reliability of solar photovoltaic panel packaging with plasma

In the production process of solar photovoltaic panels, there are a large number of processes such as coating, composite, bonding, and hot pressing. After activation by plasma technology, the wettability of the material surface can be effectively improved, thereby enhancing the overall packaging effect.

1. Plasma enhances the reliability of the "backboard" process

Solar backboards need to have superior weather resistance, high insulation, and low water permeability. The weather resistance, water and oil repellency of fluorinated materials can meet these requirements well, but their water and oil repellency are not conducive to composite with the substrate. Therefore, plasma cleaning before coating/composite with the substrate (PET) can effectively improve the reliability of fluorinated materials and substrate coating/composite.

2. Plasma enhances the reliability of "laminated parts" process

Simply put, the photovoltaic lamination process is the process of bonding the three major components of photovoltaic glass, battery cells, and backboards together through EVA.

In the lamination process, using a plasma cleaning machine to treat the fluorine film on the surface and bottom plate of photovoltaic glass can better combine with EVA and improve the bonding strength of each component of the lamination.

3. Plasma enhances the reliability of "component" processes

After the lamination is completed, we add the frame, sealant, and junction box to complete the production of our main "solar photovoltaic panel".

In this stage, using a plasma cleaning machine to treat the frame can theoretically improve the sealing effect to a certain extent.

By adding inverters, combiner boxes, brackets, batteries, etc, a complete photovoltaic system can be completed.
