INTERCONNECTOR, SOLAR CELL STRING USING INTERCONNECTOR, MANUFACTURING METHOD OF SOLAR CELL STRING, AND SOLAR CELL MODULE USING SOLAR CELL STRING

摘要

PROBLEM TO BE SOLVED: To provide an interconnector which reduces warpage occurring in a solar cell after the solar cell is connected with another solar cell and achieves excellent reliability after the connection.SOLUTION: An interconnector includes a belt like conductive member 3 electrically connecting electrodes of adjacent solar cells with each other. The conductive member includes a stress relief part X1 that forms a flat surface shape and has a notch so as to form a corner making an obtuse angle at each side end part or has the linear shaped side end parts. This structure significantly relieves stress due to a thermal expansion coefficient difference between the interconnector and the solar cells. Thus, the structure reduces warpage occurring in the solar cells and improves the reliability of the connection between the interconnector and the solar cells.
