ABSTRACT:
The present invention provides a method of forming a metal pattern on a solar cell comprising the steps of forcing a molten metal through an aligned array of orifices by use of gas pressure; vibrating the aligned array of orifices to form the molten metal issuing from the orifices into metal droplets; moving a solar cell collinearly with the aligned array of orifices; and allowing each series of metal droplets from a single orifice to fall onto a specific region of the solar cell to build up a metal layer of increasing thickness, each metal droplet being permitted sufficient time to solidify prior to allowing the next metal droplet to strike the metal layer.
