Thomas, D E

A substrate is made for silicon solar cells by heating a sheet of large-grained silicon steel at a temperature of at least about 1300/sup 0/ C. in an atmosphere of hydrogen and tungsten hexafluoride (or hexachloride) at a partial pressure ratio of hydrogen to tungsten hexafluoride of about 3 to about 6 to deposit an epitaxial layer of tungsten on said sheet of silicon steel. Epitaxial silicon can then be deposited in a conventional manner on the layer of epitaxial tungsten.
