Copper cladding method for solar cell manufacturing |
| abstract |
A method of plating copper on a substrate comprising: providing a substrate, wherein the substrate is a metallic seed layer on a silicon solar cell wafer comprising an aluminum back; and contacting the substrate with a copper plating solution comprising a source of copper ions and a conductivity salt of lithium sulfate wherein the copper plating solution has a pH between 1.7 and 3.5 and is free of chloride ions and where the back of the silicon solar cell wafer is not affected by the coating solution. |
