A system for reducing damage to solar cells during a process for depositing a conductive material on a solar cell is disclosed where an electrical bias or floating potential is applied to the solar cell; and/or an electrical bias is applied to an external electrode(s) so that charged particles of a certain type are redirected away from the solar cells, avoiding the creation of a sufficiently high reverse bias on the solar cell to breakdown the cell.
