Solar cell rear surface protective sheet

The present invention provides a solar cell rear surface protective sheet that uses a fluorine resin film in the outermost layer thereof and that minimizes the occurrence of yellowing and cracking in the fluorine resin film. Specifically, the present invention is a solar cell rear surface protective sheet that is arranged on the rear surface side of a solar battery cell and that is characterized in that: (1) the solar cell rear surface protective sheet comprises at least a first resin layer and a second layer that are stacked in this order from the outermost layer, and an innermost layer that is on the opposite side from the outermost layer is attached to a solar battery cell when attaching the solar cell rear surface protective sheet to the solar battery cell; and (2) the first resin layer contains polyvinylidene fluoride, and the crystal structure within the polyvinylidene fluoride as determined from the absorbance observed in the infrared absorption spectrum comprises 30-70% of an [Alpha]-type crystal and a remainder of a [Beta]-type crystal when the total of the [Alpha]-type crystal and the [Beta]-type crystal is 100%.
