PROBLEM TO BE SOLVED: To provide a composition, a sealing material sheet, and a solar cell module which is composed mainly of an ethylene-vinyl acetate copolymer and capable of suppressing the generation of a free acetic acid during molding, thermal bonding, and long-term use.SOLUTION: A sheet is formed using a composition which is characterized by containing a hydrotalcite compound including a hydroxyl group and a carbonate, a hindered amine-based light stabilizer, and an organic peroxide in an ethylene-vinyl acetate copolymer. The solar cell module capable of suppressing the generation of the free acetic acid and having excellent durability is provided by using the sheet as its sealing material. |
