A photovoltaic device, such as a solar cell, having improved performance is provided. In one embodiment, the photovoltaic device includes a multimetal semiconductor alloy layer located on exposed portions of a front side surface of a semiconductor substrate. The multimetal semiconductor alloy layer includes at least a first elemental metal that forms an alloy with a semiconductor material, and a second elemental metal that differs from the first elemental metal and that does not form an alloy with a semiconductor material at the same temperature as the first elemental metal. The photovoltaic device further includes a copper-containing layer located atop the multimetal semiconductor alloy layer.
