Abstract:
A photovoltaic cell such as a solar cell is disclosed. The cell comprises (a) a semiconductor substrate having a front surface, (b) one or more anti-reflection coating layers on the front surface of the semiconductor substrate, (c) a plurality of silver-containing fingers in contact with the one or more anti-reflection coating layers and in electrical contact with the semiconductor substrate; and (d) one or more base metal containing buss bars each in contact with the one or more anti-reflection coating layers and the silver-containing fingers. The base metal may be selected from one or more of copper, nickel, lead, tin, iron, indium, zinc, bismuth and cobalt. Methods for making protovoltaic cells with base metal containing buss bars are also disclosed.
