摘要:
Provided are a back side protective sheet for a solar cell, which is capable of enhancing performance of adhesion to an EVA resin as a filler used to seal the solar cell elements, of maintaining weather resistance for a long period of time, and of reducing a weight thereof; and a solar cell module including the back side protective sheet for a solar cell. The back side protective sheet (10) for a solar cell is disposed on a back side of the solar cell module (100) and includes: a first film (11) fixedly attached so as to abut a surface of a filler (7) and containing linear low-density polyethylene having a density greater than or equal to 0.91 g/cm3 and less than or equal to 0.93 g/cm3; and a second film (12) laminated on the first film (11) and disposed in an outermost layer of the back side protective sheet (10) for a solar cell, the second film (12) containing polyvinylidene fluoride and polymethyl methacrylate.
摘要(中):
提供一种用于太阳能电池的背面保护片,其能够提高作为用于密封太阳能电池元件的填充剂的EVA树脂的粘合性能,并且能够长时间地保持耐候性, 重量 以及包括太阳能电池的背面保护片的太阳能电池模块。 用于太阳能电池的背面保护片(10)设置在太阳能电池模块(100)的背面,并且包括:第一膜(11),其固定地附接以抵靠填料(7)的表面;以及 含有密度大于或等于0.91g / cm 3且小于或等于0.93g / cm 3的线性低密度聚乙烯; 和层叠在第一膜(11)上并设置在太阳能电池的背面保护片(10)的最外层中的第二膜(12),所述第二膜(12)含有聚偏二氟乙烯和聚甲基丙烯酸甲酯。
