Abstract:
1. A method of fabricating a solar cell device that incorporates the fabrication of said solar cell into a Float Glass manufacturing process comprising: a) forming a first conductive layer overlying a substrate of hot glass, during a Float Glass process; b) a first layer of silicon which has been pre-mixed with a suitable first type dopant material is then deposited at a thickness of about 10 to 50 microns; c) a second layer of silicon which has been pre-mixed with a suitable second type dopant material is then deposited at a thickness about up to 10 microns; d) the first dopant-silicon layer and the second dopant-silicon layer are then annealed by applying sufficient additional heat to melt the dopant-silicon lavers causing subsequent crystallization of the silicon, forming a non-transparent polycrystalline structure; e) then a second layer of conductive material is applied overlying the polycrystalline structure; f) then any or all layers on the glass substrate are patterned by means of photo lithography, or other means, thus describing serial and parallel circuitry of the cells.
