<p>A material for a solar cell interconnector material for a solar cell interconnector, characterized as comprising Ag and, dispersed therein, MgO or MgO and NiO. It is preferred that the weight ratio of Ag to MgO or MgO and NiO satisfies the composition: MgO: 0.03 to 3.3 wt %, balance: Ag; or the composition: MgO: 0.01 to 1.7 wt %, NiO: 0.02 to 1.3 wt %, balance: Ag. The material for a solar cell interconnector can be prepared by a method comprising melting and casting a base material comprising an Ag-Mg composition or an Ag-Mg-Ni composition, pre-rolling the resulting ingot, then subjecting the pre-rolled product to an inside oxidation treatment in an oxygen atmosphere at a temperature of 650 to 850°C under a pressure of 3 to 10 atm for 20 to 80 hr, and then rolling the treated material to a predetermined thickness. The above material has markedly advantageous over a conventional material for a solar cell interconnector in that the product made therefrom has higher resistance to heat energy, that is, does not soften by heat, and exhibits higher mechanical strength.</p> |
