SOLAR MODULE
A solar module with improved output characteristics is provided. The solar module ( 1 ) includes a photoelectric conversion unit ( 23 ), a solar cell ( 20 ) having a first electrode ( 21 ) and a second electrode ( 22 ), and a wiring member ( 32 a ). The wiring member ( 32 a ) has resin film ( 51 ) and wiring ( 52 ) arranged on the resin film ( 51 ). The wiring member ( 32 a) has a first portion ( 32 a 1 ), a second portion ( 32 a 2 ) and a bent portion ( 32 a 3 ). The first portion ( 32 a 1 ) is arranged so the wiring ( 52 ) faces the solar cell ( 20 ) side. The first portion ( 32 a 1 ) is bonded to the solar cell ( 20 ). The second portion ( 32 a 2 ) is arranged so the wiring ( 52 ) faces the reverse side from the solar cell ( 20 ). The bent portion ( 32 a 3 ) connects the first portion ( 32 a 1 ) and the second portion ( 32 a 2 ). The bent portion ( 32 a 3 ) is arranged on the solar cell ( 20 ).
1 . A solar module comprising:
a solar cell having a photoelectric conversion unit with a first main surface and a second main surface, and a first electrode and a second electrode arranged on the second main surface; and
a wiring member having resin film, and wiring arranged on the resin film and connected electrically to either the first electrode or the second electrode;
the wiring member having
a first portion arranged so the wiring faces the solar cell side and is bonded to the solar cell,
a second portion arranged so the wiring faces the reverse side from the solar cell, and
a bent portion connecting the first portion and the second portion,
the bent portion being arranged on the solar cell.
2 . The solar module according to claim 1 further comprising metal foil connected electrically to the wiring in the second portion,
the wiring being arranged on an end portion of the solar cell in one direction from one side to the other side of the end portion in another direction orthogonal to the one direction, and
the metal foil is bonded to a portion of the wiring in the other direction.
3 . The solar module according to claim 2 , wherein the metal foil is thicker than the wiring.
4 . The solar module according to claim 2 , wherein the metal foil is drawn from the solar module.
5 . The solar module according to claim 2 , wherein a plurality of solar cells are connected electrically by wiring members, and the metal foil connects the wiring members to each other.
6 . The solar module according to claim 1 further comprising:
a first protecting member arranged on the first main surface side of the solar cell;
a second protecting member arranged on the second main surface side of the solar cell and having flexibility; and
a sealing material layer arranged between the first protecting member and the second protecting member, and sealing the solar cell.
7 . The solar module according to claim 6 , wherein the sealing material layer includes a non-crosslinked resin.
8 . The solar module according to claim 1 , wherein an opening is provided in the wiring in the bent portion.
9 . The solar module according to claim 8 , wherein a plurality of openings is provided.
10 . The solar module according to claim 9 , wherein each of the first electrode and the second electrode include a plurality of interdigitated finger portions,
the wiring has
a wiring main body provided with openings, and
a plurality of linear portions connected to the wiring main body and connected electrically to the finger portions, and
the spacing of the openings is greater than the width of the linear portions.
