PURPOSE: An encapsulant sheet composition and an encapsulant sheet are provided to prevent the transmittance loss of solar light and yellowing phenomena when being exposed to the outer environment, thereby preventing the loss of generating efficiency of a solar light module. CONSTITUTION: An encapsulant sheet composition and an encapsulant sheet comprise a copolymer of ethylene and a polar monomer, a crosslinking agent, a crosslinking initiator, a silane coupling agent, a weatherability improver, and an oxidation preventing agent. The oxidation preventing agent is thiopropionate-based. A solar cell module comprises a solar cell device, an upper protecting material in the upper part of the solar cell device, a lower protecting material in the lower part of the solar cell device, and an encapsulant sheet which consists of the encapsulant composition and is attached to the upper protecting material and/or the lower protecting material. |
