BACKSIDE PROTECTIVE SHEET FOR SOLAR CELL AND SOLAR CELL MODULE COMPRISING THE SAME

摘要

Disclosed is a backside protective sheet for solar cells, which is reduced in weight and improved in close adhesion to an EVA resin as a filler used for sealing a solar cell element. This backside protective sheet for solar cells is capable of maintaining weather resistance for a long time. Also disclosed is a solar cell module comprising such a backside protective sheet. Specifically disclosed is a backside protective sheet (10) for solar cells, which is arranged on the backside of a solar cell module (100). This backside protective sheet (10) comprises a first film (11) to be fixed in contact with the surface of a filler (7) and containing a linear low-density polyethylene having a density of not less than 0.91 g/cm³ but not more than 0.93 g/cm³, and a second film (12) arranged on the first film (11) so as to be the outermost layer of the backside protective sheet (10) for solar cells and containing a polyvinylidene fluoride and a polymethylmethacrylate.
