<p>PROBLEM TO BE SOLVED: To provide an inexpensive sealing material film for solar cell with good productivity. SOLUTION: In a solar cell module where glass 10, an ethylene-vinyl acetate copolymer (EVA) sheet layer 26 as a solar cell sealing material film, a silicon power generation element 12, an EVA sheet layer 28 as the solar cell sealing material film and a back cover 14 are incorporated, heated and press-fitted. An EVA sheet has the melt flow rate of not more than 14 g/10 min. and includes organic peroxide whose half-value period at 130 deg.C is not more than one hour. The EVA sheet layer 28 includes coloring agent such as titanium white. A metal layer of the back cover 14 such as aluminium foil, a plastic film layer and the EVA sheet layer are bonded.</p> |
