Photovoltaic (PV) adhesives utilize moisture in the air to cure at room temperature to provide excellent bonding and sealing properties for solar PV module outer frame and junction box applications. When manufacturing and assembling PV modules, it is necessary to select adhesives with excellent properties such as high light transmission, weatherability, and high adhesion to ensure the quality and long-term stability of PV modules. The importance of adhesives in PV modules is mainly reflected in the following aspects:
