Embodiment 1
[0084] An adhesive for dry lamination was applied by gravure coating on one side of a rolled electrodeposited copper foil having a thickness of 35 μm. The adhesive for dry lamination was obtained by mixing 100 parts by mass of LX500 manufactured by DIC Corporation and 10 parts by mass of KW75 manufactured by DIC Corporation, and diluting them appropriately with ethyl acetate.
[0085] Put the electrolytic copper foil coated with the adhesive in a drying oven, volatilize the excess solvent, and then bond a polyterephthalene film with a thickness of 50 μm on the side coated with the adhesive. The ethylene glycol formate film was laminated by dry lamination to obtain a laminate. The resulting laminate was aged at 40°C for 3 days.
[0086] On the laminated material of the electrolytic copper foil (conductor layer) and the polyethylene terephthalate film (insulating resin film) obtained as described above, the bonding pad ( Electrode) position corresponding to the position, using...
Embodiment 2
[0089] An EVA film with a thickness of 50 μm was adhered to one surface of a roll-shaped electrodeposited copper foil having a thickness of 35 μm, followed by bonding by a heat lamination method to obtain a laminate. Heat lamination was performed using a heating roll heated to 150° C. and a rubber roll arranged in parallel therewith, and sandwiching the laminate of the electrolytic copper foil and the EVA film between the heating roll and the rubber roll. A laminated material of an electrolytic copper foil and an EVA film was obtained by applying pressure between the heating roller and the rubber roller to the extent that wrinkles and warping would not occur.
[0090] On the laminated material of electrolytic copper foil (conductor layer) and EVA film (insulating resin film) obtained above, at the position corresponding to the position of the pad (electrode) of the rear contact type solar cell , use a punching machine to set a through hole with a diameter of 1mm.

[0093] An adhesive for dry lamination was applied by gravure coating on one side of a rolled electrodeposited copper foil having a thickness of 35 μm. The adhesive for dry lamination was obtained by mixing 100 parts by mass of LX500 manufactured by DIC Corporation and 10 parts by mass of KW75 manufactured by DIC Corporation, and diluting them appropriately with ethyl acetate.
[0094] Put the electrolytic copper foil coated with the adhesive in a drying oven, volatilize the excess solvent, and then bond a polyterephthalene film with a thickness of 50 μm on the side coated with the adhesive. Ethylene glycol formate film, laminated by dry lamination.
[0095] Next, an EVA film having a thickness of 50 μm was bonded to the polyethylene terephthalate film by a dry lamination method to obtain a laminate. The resulting laminate was aged at 40°C for 3 days.
[0096] On the laminate of the electrolytic copper foil (conductor layer), polyethylene terephthalate film (insulating resin ...
