Abstract
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.
