<p>Provided is a material to be used for a solar cell interconnector which is used for connecting cells in a solar cell module. The interconnector material contains, in mass, parts per million, at least Zr or Mg by 3ppm or more but not more than 20ppm and O by 5ppm or less, and has the rest composed of Cu and an unavoidable impurities and a residual resistance ratio of 300 or more. A solar cell interconnector (32), which interconnects cells (31) in a solar cell module (30), is composed of the solar cell interconnector material, formed as a rectangular wire having a rectangular cross-section, with a lead-free solder plated layer at least on one surface of a main surface extending in the extending direction of the rectangular wire.</p> |
