Abstract
A solar cell backsheet including: a support which has a thickness of 120 μm to 350 μm; a first polymer layer which is formed on one surface of the support by coating, which includes a polymer, and which has a thickness of 0.5 μm to 12.0 μm; and a second polymer layer which is formed, by coating, on the opposite side of the side of the support provided with the first polymer layer, which includes a fluorinated resin or a silicone-based resin, and which has a thickness of 0.2 μm to 15.0 μm.

A backsheet for a solar cell, the backsheet comprising:
- a support which has a thickness of 120 μm to 350 μm and which has a ratio of an elongation at break after 50 hours of storage at 120° C. and 100% RH, to an elongation at break before the storage, of 77% or more;
- a first polymer layer which is formed on one surface of the support by coating, which comprises a polymer, and which has a thickness of 0.5 μm to 12.0 μm;
- and
- a second polymer layer which is formed on a surface on an opposite side from the surface of the support on which the first polymer layer is provided by coating, which comprises a fluorinated resin or a silicone-based resin, and which has a thickness of 0.2 μm to 15.0 μm.
