Solar cell module manufacturing method and solar cell module

1. A method of manufacturing a solar cell module,

the solar cell module including:

a bridge wiring member that extends in a first direction, the bridge wiring member dividing the solar cell module into a first region and a second region;

a first solar cell string that extends in the first region and in a second direction different from the first direction; and

a second solar cell string that extends in the second region and in the second direction, wherein

the first solar cell string includes a first solar cell provided on a side of the bridge wiring member, and

the second solar cell string includes a second solar cell provided on a side of the bridge wiring member and facing the first solar cell, wherein the first solar cell and the second solar cell sandwich the bridge wiring member,

the method comprising:

preparing a first cell film having (1) a first adhesive on a surface of the first cell film, and (2) a plurality of first cell wiring members in the first adhesive;

preparing a second cell film having (1) a second adhesive on a surface of the first cell film, and (2) a plurality of second cell wiring members in the second adhesive;

attaching the plurality of first cell wiring members to the first solar cell by attaching the first adhesive of the first cell film to the first solar cell;

attaching the plurality of second cell wiring members to the second solar cell by attaching the first adhesive of a second cell film to the second solar cell;

sandwiching the plurality of first cell wiring members from the first solar cell and the plurality of second cell wiring members from the second solar cell between a wiring member film and the bridge wiring member; and

connecting the plurality of first cell wiring members and the plurality of second cell wiring members to the bridge wiring member by applying heat to at least the plurality of first cell wiring members, the plurality of second cell wiring members, and the bridge wiring member by induction heating.

2. The method of manufacturing a solar cell module according to claim 1 , wherein

the bridge wiring member includes a surface having a length in the first direction and a width in the second direction, and

the sandwiching includes sandwiching the plurality of first cell wiring members and the plurality of second cell wiring members between one wiring member film and the surface of the bridge wiring member.

3. The method of manufacturing a solar cell module according to claim 2 , wherein the sandwiching causes the plurality of first cell wiring members and the plurality of second cell wiring members to mutually overlap in the second direction.

4. The method of manufacturing a solar cell module according to claim 1 , wherein

the bridge wiring member includes a first surface having a length in the first direction and a width in the second direction and a second surface opposite to the first surface,

the wiring member film includes a first wiring member film and a second wiring member film, and

the sandwiching includes sandwiching the plurality of first cell wiring members between the first wiring member film and the first surface of the bridge wiring member and sandwiching plurality of second cell wiring members between the second wiring member film and the second surface of the bridge wiring member.

5. A solar cell module comprising:

a bridge wiring member that extends in a first direction without being bent, the bridge wiring member dividing the solar cell module into a first region and a second region;

a first solar cell string that extends in the first region and in a second direction different from the first direction; and

a second solar cell string that extends in the second region and in the second direction, wherein

the bridge wiring member includes a first surface having a length in the first direction and a width in the second direction and a second surface opposite to the first surface,

the first solar cell string includes a first solar cell provided on a side of the bridge wiring member,

the second solar cell string includes a second solar cell provided on a side of the bridge wiring member and facing the first solar cell, wherein the first solar cell and the second solar cell sandwich the bridge wiring member, and

the solar cell module further comprises:

a plurality of first cell wiring members that (1) extend from the first solar cell toward the bridge wiring member, (2) extend across the first surface of the bridge wiring member in the second direction, and (3) are connected to the first surface, and

a plurality of second cell wiring members that (1) extend from the second solar cell toward the bridge wiring member, (2) extend across the second surface of the bridge wiring member in the second direction, and (3) are connected to the second surface.
