Abstract: Method for manufacturing a solar cell module in which a light-receiving side sealing film 13A and a backside sealing film 13B are each formed of a different resin composition from each other selected from a resin composition A and a resin composition B, both of the sealing films are heated when the pressurizing is initiated so as to reach to a minimum temperature X° C. and a maximum temperature Y° C., the resin composition A has a viscosity of 5.0×104 Pa·s or less at the temperature X° C., and the resin composition B has a viscosity of 7.0×104 Pa·s or less at the temperature X° C. and has a viscosity of 2.0×104 Pa·s or more at the temperature Y° C.

Abstract: To provide a sealing film for a solar cell, which can be effectively formed and is capable of preventing wraparound even if heating is performed in a wide temperature range when members of the solar cell module are integrated. A pair of sealing films 13A and 13B for a solar cell including a light-receiving side sealing film 13A formed from a resin composition A; and a colored backside sealing film 13B formed from a resin composition B, wherein a temperature at which the resin composition B has a viscosity of 50,000 Pa·s is 95° C. or lower, and the resin composition B has a viscosity higher than that of the resin composition A at 80° C. and 100° C.

Abstract: There is provided a cured sheet and a laminate having the same, wherein the cured sheet is prepared by curing a laminate forming sheet containing an ethylene-vinyl acetate copolymer and a polyethylene, excellent in adhesion durability and has a sufficient flexibility even in the case of a high content of the polyethylene. A cured sheet constituting a laminate and a laminate having the same, wherein the cured sheet is prepared by curing through cross-linking a laminate forming sheet comprising a composition containing an ethylene-vinyl acetate copolymer, a polyethylene and an organic peroxide; a weight ratio of the ethylene-vinyl acetate copolymer (EVA) to the polyethylene (PE) (EVA:PE) is in a range of 3:7 to 8:2; and the cured sheet has a sea-island structure wherein the ethylene-vinyl acetate copolymer constitutes a sea phase and the polyethylene constitutes an island phase.

Abstract: To provide a composition for producing a sheet for forming a laminate, which contains an ethylene-vinyl acetate copolymer and a polyethylene resin, by which the above-described problems in the width of the temperature range in which a processable viscosity range is obtained and the like are improved and which excels in processing properties such as a film-forming property when producing a sheet, and a sheet for forming a laminate using this. A composition for producing a sheet for forming a laminate, which contains an ethylene-vinyl acetate copolymer and polyethylene, wherein the composition has a sea-island structure in which the ethylene-vinyl acetate copolymer is a sea phase and the polyethylene is an island phase, and a sheet for forming a laminate using this.
