Title: SOLAR CELL REAR SURFACE SEALANT SHEET SET, SOLAR CELL MODULE AND METHOD FOR PRODUCING SOLAR CELL MODULE
Abstract:
This solar cell rear surface sealant sheet set is positioned between a solar cell element and a rear-side protective member, is used to seal the non-light-receiving side of the solar cell element, and is equipped with a transparent sealant sheet and a colored sealant sheet. The transparent sealant sheet contains at least one type of ethylene copolymer selected from an ethylene alpha-olefin copolymer and an ethylene polar monomer copolymer, and is positioned on the solar cell element side. The colored sealant sheet contains a coloring agent and at least one type of ethylene copolymer selected from an ethylene alpha-olefin copolymer and an ethylene polar monomer copolymer, and is positioned on the rear-side protective member side. When sealing the solar cell element, the transparent sealant sheet and the colored sealant sheet are used by being laminated to one another.
