Abstract:
1. A method of connecting solar battery cells that are each provided with a front-face electrode on a front face thereof and a back-face electrode on a back face thereof, wherein the method comprises the steps of: (a) preparing a wiring member having first and second end portions, including a strip-like conductive substrate and an adhesive layer provided on one face of the conductive substrate, and bonding the adhesive layer on the first end portion of the wiring member with one of a front-face electrode or with a back-face electrode of one solar battery cell, wherein the adhesive layer comprises a resin composition that includes thermosetting resin; (b) turning the second end portion of the wiring member, having gone through step (a), one time around a central axis along a longitudinal direction of the wiring member so a turned-around part is disposed between the first end portion and the second end portion so that an adhesive layer surface of the second end portion is opposite in orientation to an adhesive layer surface of the first end portion; and (c) bonding the adhesive layer of the second end portion of the wiring member, having gone through step (b), with an electrode of a second solar battery cell having an opposite polarity to the electrode of the one solar battery cell that has been bonded in step (a) so that the first and second end portions of the wiring member are disposed along a straight line defined by the central axis of the wiring member.
