摘要: A method and composition for plating metal contacts on photovoltaic solar cells is described. The cell is immersed in an aqueous bath containing platable metal ions and a solubilizing agent for aluminum or aluminum alloy ions from the back side of the solar cell. The cell is then exposed to light, causing the two sides of the cell to become oppositely charged. The metal ions are plated without requiring an external electrical contact.
