Abstract
A photovoltaic module having non-contacting bus bars and methods of making non-contacting bus bars are disclosed. The fingers are screen printed on the substrate using a paste. The bus bar(s) can be formed over the fingers using a number of techniques that do not dissolve through the passivation layer of the substrate. The bus bar(s) can be screen printed over the fingers using a second paste that is more viscous and/or conductive than the first paste. The bus bar(s) can be a conductive trace that is deposited over the fingers. The bus bar(s) can be a metal wire coated with solder or paste that is positioned on the fingers. Metal plating techniques may also be used to thicken the fingers and/or bus bars. One or more doping steps may be used to form selective emitters under the fingers and bus bar.
