The purpose of the present invention is to provide: a sealing material sheet for solar cell modules, which is capable of stably forming a sealing material layer that has excellent adhesion and high crosslinking density, and which enables the production of a solar cell module that has high reliability for long-term use; and a solar cell module which uses this sealing material sheet for solar cell modules. A sealing material sheet (6) for solar cell modules contains an ethylene/α-olefin copolymer, an organic peroxide and a silane coupling agent, and satisfies condition (1) 5.4 ≤ (A × B)/C ≤ 10.1 and condition (2) 6.0 × 10-3 ≤ A × (D/E) ≤ 1.0 × 10-2. In this connection, A is the theoretical amount of oxy radicals generated from one molecule of the organic peroxide; B is the molar quantity of the organic peroxide; C is the molar quantity of the silane coupling agent; D is the content (parts by mass) of the organic peroxide relative to 100 parts by mass of the ethylene/α-olefin copolymer; and E is the molecular weight of the organic peroxide. A solar cell module (5) uses this sealing material sheet (6). |
