Patent ID: 8298363

Claim:
A method of manufacturing a solar cell module including a solar cell string between a light-receiving-surface-side protection material and a back-surface-side protection material, the solar cell string being formed of a plurality of solar cells and wiring members electrically connecting the plurality of solar cells to one another, the plurality of solar cells each having a light receiving surface from which light enters, and a back surface provided on a side opposite to the light receiving surface, the method comprising: a step A of disposing one of the wiring members on the light receiving surface of one solar cell of the plurality of solar cells, with a thermosetting resin adhesive interposed therebetween, the wiring member being to be connected to a solar cell adjacently located on one side of the one solar cell, and disposing another one of the wiring members on the back surface of the one solar cell with the resin adhesive interposed therebetween, the wiring member being to be connected to a solar cell adjacently located on the other side of the one solar cell; a step B of bonding the wiring members to the one solar cell by heating the resin adhesive at a temperature higher than a softening temperature of the resin adhesive but lower than a hardening temperature of the resin adhesive; a step C of bonding the wiring members to all the plurality of solar cells by repeating the step A and the step B alternately; and a step D of hardening the resin adhesive by heating the resin adhesive at a temperature equal to or higher than the hardening temperature of the resin adhesive with the resin adhesive being pressed against the wiring members.
