NOVELTY - A solar cell sealing sheet (1) consists of sealing sheet (11) arranged between light-receiving surface side protection component (14) and solar cell element (16), and sealing sheet (12) arranged between light-receiving surface side protection component and back surface side protection component (15). The sealing sheet (11) consists of ethylene-( alpha )-olefin copolymer (a1), and sealing sheet (12) consists of ethylene-polar monomer copolymer (b1), 0.05-2 pts. wt. epoxy group-containing silane coupling agent (b2), and 0.6-2 pts. wt. acid acceptor (b3).    USE - Sheet is used for sealing solar cell modules (claimed) for power generation equipment, outdoors and indoors e.g. roof of residence and camps, and auxiliary power supply of motor vehicle batteries.    ADVANTAGE - The sheet has excellent adhesiveness with respect to metal electrode and solder of solar cell even at high temperature and high humidity for long period of time, and economically provides solar cell module with suppressed potential induced degradation, excellent productivity, power generating efficiency and lifetime.    DETAILED DESCRIPTION - A solar cell sealing sheet consists of a sealing sheet arranged between light-receiving surface side protection component and solar cell element, and a sealing sheet arranged between light-receiving surface side protection component and back-surface side protection component. The sealing sheet (11) consists of ethylene-( alpha )-olefin copolymer, and sealing sheet (12) consists of ethylene-polar monomer copolymer (b1), and 0.05-2 pts. wt. epoxy group-containing silane coupling agent (b2) with respect to 100 pts. wt. ethylene-polar monomer copolymer, and 0.6-2 pts. wt. acid acceptor (b3) chosen from metal oxide, metal hydroxide, metal oxycarbide, and composite metal hydroxide. An INDEPENDENT CLAIM is included for solar cell module, which has sealing layer between light-receiving surface side protection component and back surface side protection component. The sealing layer has back surface side sealing layer provided between light-receiving surface side sealing layer and the back surface side protection component, where light-receiving surface side sealing layer consists of sheet containing sealing sheets (11 and 12).
