Abstract
The disclosure illustrates a ribbon like photovoltaic cell that is formed by first applying a thin layer of tungsten or other conductive, temperature resistant material on a base ribbon of high temperature resistant, and electrically non-conductive material. A thin coat of silicon up to several atoms thick is deposited over the ribbon and/or tungsten to enable the ribbon to be drawn through a bath of molten silicon to grow a layer of silicon which is subsequently doped with impurities. A conductive grid over the silicon and a connector through a perforation in the base ribbon enable the cell to be connected in an electrical circuit to produce a current flow. The use of the base ribbon enables continuous flow process techniques to greatly reduce the cost of production for a photovoltaic cell. In addition, the base ribbon may be split lengthwise after processing on both sides to enable the production of two (2) ribbons.
