Abstract

The present invention provides a material for an interconnector of a solar cell, comprising copper; calcium or strontium; and the balance silver. Desirable contents in the alloy are 0.08-0.8 by atomic percent with respect to copper, 0.015-0.15 by atomic percent with respect to calcium if added, and 0.005-0.2 by atomic percent with respect to strontium if added.

Claims

exact text as granted — not AI-modified
1 . A material for an interconnector of a solar cell, comprising copper; calcium or strontium; and the balance silver.
