Technical Field

Background
With the continuous development of society, environmental pollution and energy shortage are two major problems facing human beings. The green and low carbon is an effective way for realizing 'carbon peak reaching and carbon neutralization', the solar energy is inexhaustible renewable clean energy, and the conversion of the clean and renewable solar energy into electric energy by utilizing the solar cell is one of effective methods for solving the two problems. At present, the generating efficiency of a photovoltaic module is difficult to improve and is always maintained between 18% and 19%, and how to improve the photoelectric conversion efficiency of a photovoltaic cell becomes the focus of attention of the world photovoltaic industry. In order to improve the utilization rate of sunlight, the transparent EVA film on the back is usually replaced with a white EVA film with high reflectivity, thereby increasing the generated power of the cell. However, the white EVA film is prone to glue overflow and wrinkle during the lamination process of the module, which not only affects the appearance but also limits the power improvement, and generally needs to improve the lamination appearance through pre-crosslinking, but the pre-crosslinking inevitably reduces the bonding strength between the back sheet and the film, increases the film production process, increases the production cost, and has potential risk of power attenuation due to the added white pigment reducing the volume resistivity.
