Title:

INTERCONNECTOR FOR SOLAR CELLS, AND SOLAR CELL MODULE

Document Type and Number:

WIPO Patent Application WO/2012/165348

Kind Code:

A1

Abstract:

The purpose of the present invention is to provide an interconnector for solar cells, which reduces the stress acting on a solar cell and suppresses warping and cracking of the solar cell. An interconnector for solar cells of the present invention is characterized by comprising an electrically conductive wire part and a surface layer that is formed on at least one wide surface of the electrically conductive wire part. The interconnector for solar cells is also characterized in that the surface layer has a function of reducing the stress that is caused by the difference between the thermal expansion coefficient of the electrically conductive part and the thermal expansion coefficient of a solar cell, said stress being generated when the interconnector is joined to the solar cell.
