提高太阳能电池板背膜材料的表面能可以对太阳能电池板进行更好的封装,从而对生产出高性能、长寿命的太阳能电池板具有重要意义.为此,用空气中介质阻挡放电(DBD)产生的常压低温等离子体对太阳能电池板背膜材料进行表面改性,通过接触角测量仪测量了DBD改性前后背膜表面亲水性和表面能的变化,通过扫描电子显微镜(SEM)和全反射傅立叶红外光谱仪(ATR-FTIR)分析了改性前后背膜表面物理结构和化学成分的变化,并研究了处理后材料的退化效应及功率密度的影响.接触角测量结果表明,经过DBD等离子体处理后,背膜材料的表面能提高,亲水性增强,接触角和表面能均在一定处理时间达到饱和值;SEM观测发现,处理后背膜表面的粗糙度增大;FTIR分析表明,处理后的背膜表面的化学基团发生变化,引入了含氧极性基团.处理后的材料在空气中放置时会出现退化效应,但即使放置6 d后材料表面水接触角仍远低于处理前的值.增大DBD处理的功率密度,利用更少的处理时间就能得到同样的处理效果.

Improving the surface energy of backsheet materials can lead to better encapsulation of the solar panel, which is of important significance for the production of high-performance and long-life solar panel.Consequently, the surface of backsheet was modified using non-thermal plasma generated by dielectric barrier discharge (DBD) at atmospheric pressure air.The changes of hydrophilicity and surface energy of untreated and DBD plasma treated samples were studied by means of contact angle measurement, and the changes of physical structure and chemical composition on the surface were analyzed by scanning electron microscopy (SEM) and attenuated total reflectance Fourier transformed infrared spectroscopy (ATR-FTIR) ,moreover, the aging effect and the influence of power den-sity on the surface modification were studied.Results show that, after the DBD treatment, the surface energy and hydrophilieity are increased greatly, and both of them reach a saturation value as the treatment time increases to a certain value.The results of SEM observations show that surface roughness is increased after DBD treatment, and the results of FTIR reveal that oxygen-containing polar groups are introduced onto the material surfaces.Aging effect occurs when the treated materials are exposed in air, but the value of water contact angle is still much lower than that of the untreated materials even after six days storage.By increasing the power density of DBD treatment, less treatment time is needed to obtain the same treatment effects.
