Abstract
Disclosed is a solar cell module that includes: a plurality of solar cells; wiring material electrically connecting solar cells with each other; and resin adhesive that bonds solar cells and wiring material together. Solar cells each include photoelectric conversion body and electrode. Electrode includes finger electrode. Finger electrode extends in direction y orthogonal to direction x in which wiring material extends. In bonding area of finger electrode bonded to wiring material, an end portion on one side in direction y in which finger electrode extends is bonded to wiring material with lower bonding strength than at least part of the other portion of bonding area.
Claims14
A solar cell module comprising:
- a plurality of solar cells each including a photoelectric conversion body and an electrode provided on a surface of the photoelectric conversion body;
- a wiring material that electrically connects the plurality of solar cells with each other;
- and
- a resin adhesive that bonds the solar cells and the wiring material together, wherein
- the electrode includes a finger electrode extending in a direction orthogonal to a direction in which the wiring material extends, and
- in a bonding area of the finger electrode bonded to the wiring material, an end portion on a first side in the direction in which the finger electrode extends is bonded to the wiring material with lower bonding strength than at least part of the other portion of the bonding area.
A solar cell comprising:
- a photoelectric conversion body;
- and
- an electrode provided on a surface of the photoelectric conversion body and being a portion to which a wiring material is to be connected, wherein
- the electrode includes a finger electrode extending in one direction,
- the finger electrode includes a portion of which a thickness decreases from one side to the other side in the one direction, and
- the portion of the finger electrode is a portion to be connected to the wiring material.
A solar cell, comprising:
- a photoelectric conversion body;
- a plurality of finger electrodes provided on a surface of the photoelectric conversion body;
- and
- a bas bar electrode that intersects at least one finger electrode at an angle on a surface of the photoelectric conversion body, wherein the angle is not perpendicular to a longitudinal direction of the plurality of the finger electrode;
- wherein at least one finger electrode comprises:
- an edge portion farthest from the bus bar electrode;
- and
- an intersection portion that the finger electrode intersects the bus bar electrode, wherein a width of the intersection portion is larger than that of the edge portion.
