Publication number: 20090308446Abstract: A backside electrode layer and a fabricating method thereof are applicable for fabricating a solar cell. The backside electrode layer includes a first electrode layer and a second electrode layer. The first electrode layer is formed on a substrate and has a thickness smaller than 15 ?m. The second electrode layer having patterns is formed on the first electrode layer. The first and second electrode layers are fabricated by a cofiring process.
