Sealing material sheet and a solar cell module for a photovoltaic module

Disclosed is excellent adhesion and high crosslink density can stably form a sealing material layer having a solar cell module sealing material sheet capable of producing a solar cell module with high reliability in long-term use , and it aims to provide a solar cell module using the sealing material sheet. Wherein A EVA, an organic peroxide and a silane coupling agent, the condition (1) 2.5 ≦ (A × B) /C≦3.5, and conditions (2) 3.0 × Further, the solar cell module using the sealing material sheet. .BACKGROUND
