Abstract: There is disclosed a silver alloy foil for an interconnector of a solar cell. The silver alloy contains 10 ppm to 1,000 ppm of calcium; 10 ppm to 750 ppm of at least one element selected from the group consisting of beryllium, lanthanum and indium; balance silver and unavoidable impurities. The alloy is less susceptible to softening even when the solar cell is exposed to temperature cycling. If calcium is further added, the hardness does not decrease even with the passage of time, to thereby exhibit superior characteristics for a prolonged period of time.
