SOLAR BATTERY RECTANGULAR CONDUCTOR, METHOD FOR FABRICATING SAME AND SOLAR BATTERY LEAD WIRE

摘要

A rectangular conductor for a solar battery and a lead wire for a solar battery, in which warping or damaging of a silicon crystal wafer is hard to occur at the time of bonding a connection lead wire even when a silicon crystal wafer is configured to have a thin sheet structure, can be provided. A conductor 1 having a volume resistivity equal to or less than 50 μΩ·mm, and a 0.2% yield strength value equal to or less than 90 MPa in a tensile test is formed into a rectangular conductor 10 for a solar battery having a rectangular cross section, and a surface of the rectangular conductor 10 for a solar battery is coated with a solder plating film 13, to provide a lead wire 20 for a solar battery.
