摘要: Provided is a sheet set for encapsulating a solar cell which is disposed between a light-receiving surface side protective member and a back surface side protective member, and is used for encapsulating a solar cell element and a wiring material. The sheet set for encapsulating a solar cell includes a first encapsulating material sheet disposed on a light-receiving surface side and a second encapsulating material sheet disposed on a back surface side. A storage elastic modulus (P1) of the first encapsulating material sheet before a cross-linking treatment and a storage elastic modulus (P2) of the second encapsulating material sheet before the cross-linking treatment satisfy a relationship of the following Expression (1), at 120° C. when solid viscoelasticity is measured under conditions of a measurement temperature range of 25° C. to 180° C., a frequency of 1.0 Hz, a temperature rising rate of 10° C./minute, and a shear mode.
