Abstract:
A glass sheet has an electrically conductive film having a sheet resistance in the range of 9.5 to 14.0 ohms/square; an emissivity in the range of 0.14 to 017 and an absorption coefficient of greater than 1.5×10cmin the wavelength range of 400-1100 nanometers, and a surface roughness of less than 15 nanometers Root Means Square. A glass sheet of another embodiment of the invention has an electrically conductive film having a phosphorous-fluorine doped tin oxide pyrolytically deposited film on the surface of the glass sheet, wherein the ratio of phosphorous precursor to tin precursor is in the range of greater than 0-0.4. The coated glass sheets of the invention can be used in the manufacture of multi sheet insulating units, OLEDs and solar cells.
