[0001] The present invention relates to the technical field of photovoltaic module packaging, and in particular to a silicone gel packaging device of a photovoltaic module and a packaging method thereof. Background Art

[0002] In order to improve the economic competitiveness of solar panels, the most effective way is to extend their service life. At present, the most important factor affecting the service life of solar panels is the sealing material EVA. The corrosion of EVA, the breakage of cells and connections are the main reasons for the attenuation (reduction of service life) of solar modules.

[0003] At present, silicone gel is the best substitute for EVA. It is superior to traditional EVA in terms of light transparency, operating temperature range, and no corrosive impurities (such as acetic acid in EVA). Commonly used silicone gel is mainly composed of methyl diene silicone oil and methyl hydrogen silicone oil containing catalysts. Silicone gel encapsulation is to spray the liquid silicone gel compound on the photovoltaic module and solidify it at room temperature or under heating conditions to become a thermosetting polymer insulation material with excellent performance.
