Abstract
The invention relates to the technical field of back film materials of solar cell panels, in particular to a processing method for improving the surface energy of a back film of a solar cell panel. The processing method comprises the following steps that (1) surface modification is conducted on the back film materials of the solar cell panel through ordinary pressure low-temperature plasma generated through air dielectric barrier discharge (DBD); (2) changes of the surface hydrophilicity and the surface energy of the back film before DBD modification and the surface hydrophilicity and the surface energy of the back film after DBD modification are measured through a contact angle gauge; (3) changes of the surface physical structure and the chemical components of the back film before DBD modification and the surface physical structure and the chemical components of the back film after DBD modification are analyzed through a scanning electron microscope (SEM) and an attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR). According to the processing method for improving the surface energy of the back film of the solar cell panel, the degeneration effect can appear when the processed materials are put in air, but the surface water contact angle of the materials is still far smaller than the surface water contact angle of the materials before processing is conducted after the processed materials are put in air six days.
