Background As a core energy conversion component of a photovoltaic module, a solar cell is generally made of a semiconductor material such as silicon, thin film, or the like. Although the materials have good photoelectric properties, the physical structure of the materials is fragile, and the materials are extremely easy to erode and destroy by the external environment in the long-term outdoor operation process. Therefore, reliable encapsulation protection is applied to the surface of the battery piece, and the method is a key link for guaranteeing long-term stable operation of the photovoltaic module. In the solar module packaging process, edge sealing glue plays a crucial role.
