Being the inter- connector material for the solar battery which is used as the inter- connector for the solar battery which joints

摘要

PROBLEM TO BE SOLVED: To provide an interconnector material for solar cells which uniformly absorbs heat stress generated upon solder joining and can prevent the generation of the warpage of cells, and a method for producing the same, and an interconnector for solar cells composed of the interconnector material for solar cells.;SOLUTION: Disclosed is an interconnector material for solar cells used as an interconnector 32 for solar cells connecting cells 31 in a solar cell module 30, which contains, by mass, 3 to 20 ppm at least one kinds selected from Zr and Mg and ≤5 ppm O, and the balance Cu with inevitable impurities, and has the average crystal grain size of ≥300 μm.;COPYRIGHT: (C)2010,JPO&INPIT
