The packaging adhesive film plays roles of bonding protection and the like in the assembly, more and more battery pieces are used in the photovoltaic assembly, the performances of various battery pieces are different, and the requirements on the packaging adhesive film are different; for example, the P-type cell needs a glue film with high PID resistance; the heterojunction battery piece provided with the circular welding strip needs an adhesive film with a non-slip surface, the CIGS battery piece is not sensitive to heat and needs low-temperature lamination, and the like, so that the requirement on the packaging adhesive film is higher and higher. In the field of solar cells, some cells are not resistant to UV light, so a UV cut-off type adhesive film is required to protect the cells. UV light can generate electricity but can damage polymer materials such as adhesive films, backing sheets, and the like. From the EQE curves of the various cells, the EQE response in the UV light band is small, and the EQE response in the visible light region is large. Therefore, if the UV light harmful to the high polymer material is converted into visible light, the material can be protected from the UV light, and the power of the component can be improved. After the UV light is converted into visible light, the EQE response is high, and the power of the component is high.
