Patent ID: 8148192

Claim:
A method of fabricating a transparent or semi-transparent solar cell device that incorporates the fabrication of said solar cell into a Float Glass manufacturing process comprising: a) forming a first transparent or semi-transparent 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 less than 4 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 of less than 4 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 layers causing subsequent crystallization of the silicon, forming a transparent polycrystalline structure; e) then a second layer of transparent or semi-transparent conductive material is applied overlying the polycrystalline structure; f) then the second layer of transparent or semi-transparent conductive material is etched or patterned exposing cells and describing serial and parallel circuitry of the cells.
