Abstract
An object is to provide a solar cell module capable of reducing warping of each solar cell due to a linear expansion coefficient difference between the solar cell and a wiring line member to prevent damages effectively without raising any cost increase. A solar cell module comprises a plurality of solar cells and is constituted by electrically connecting adjacent solar cells to one another by wiring line members, a base material of the wiring line member has a plastic strain of 2% or less in a drawing direction, and the solar cell is constituted of a crystalline wafer having a thickness of 200 microns or less.
Claims6
A solar cell module comprising a plurality of solar cells and constituted by electrically connecting adjacent solar cells to one another by wiring line members,
- wherein a base material of the wiring line member has a plastic strain of 2% or less in a drawing direction.
A method of manufacturing a solar cell module, comprising the step of:
- electrically connecting adjacent solar cells to one another by wiring line members, the method further comprising:
- the step of correcting linearity of each wiring line member prior to the step of connecting the wiring line members to the solar cells, the correcting step comprises the step of pulling the wiring line member in a drawing direction within range in which a plastic strain of a base material of the wiring line member in the drawing direction is 2% or less.
