ABSTRACT:
A solar cell fabrication procedure is described in which a silicon substrate having a layer of silicon nitride on one side is selectively coated with a paste that contains silver metal and a glass frit. Upon heating to a temperature in excess of 760 degrees C. for a time not exceeding about 20 seconds, the glass penetrates the silicon nitride and the substrate surface is metallized by the silver metal, with the result that the finished solar cell has a fill factor of at least about 0.75 even though the paste contains no phosphorus.
