Disclosed herein are CdTe-based solar cells that are successfully removed from their glass superstrate through a combination of lamination to a backsheet followed by thermal shock.

A solar cell module includes a solar cell, a wiring member electrically connected to the solar cell, a light-receiving-surface encapsulant and a back-surface encapsulant that cover the solar cell, a light-receiving-surface protecting member; and a back-surface protecting member. The back-surface protecting member does not contain a metal foil. A back-side metal electrode contacts the back-surface encapsulant. The arithmetic mean roughness of the surface of the back-side metal electrode that contacts the back-surface encapsulant is less than 0.1 μm. The back-surface encapsulant comprises a crosslinked olefin resin.
