[0002] The life expectancy of solar photovoltaic modules is 25-30 years. During this period, the modules must stand out from the crowd, facing continuous natural challenges such as temperature surges and drops, moisture interweaving and soaking, and resisting the threat of possible defects in the process. In the face of various environmental challenges, many modules are protected by films. Among them, POE film is a material that has the processing convenience of plastics and the durability and barrier properties of rubber. It can be called a perfect combination of plastics and rubber.

[0003] Existing photovoltaic cells need to be packaged during use. The specific operation process is to place the cell on top of the backplane, then fix the film through an adsorption device, and then cover the film on top of the cell to complete the film coating work.
