Abstract
A method and apparatus are provided for forming grid electrodes for solar cells, the method and apparatus essentially involving dispensing a viscous ink through a hollow pen tip onto a selected horizontally oriented solar cell blank, so that the discharged ink forms a ribbon or line on the blank, with the pen tip being spaced far enough above the solar cell blank so that it does not ride on the deposited ribbon or line, whereby the width and height of the written ribbon or line are not determined by the o.d. of the pen tip or any pressure exerted by the pen tip.
