Embodiment 1-15 and 16-23
[0055] Float glass production was used to manufacture float glass ribbons with a thickness of 6 mm. During the production of float glass ribbons, the specified coatings were molded in thicknesses (Angstroms) shown in Table 1 by conventional chemical vapor deposition methods to be continuously applied to glass substrates in float tanks. The precursor mixture for the different tin oxide coatings included dimethyltin dichloride, oxygen, water and helium as a carrier gas. The precursor mixture for silica coating includes monosilane, ethylene and oxygen and a carrier gas. A precursor mixture for doped zinc oxide includes a Zn precursor such as diethylzinc (DEZ), an oxygen source such as IPA (isopropanol), and a suitable aluminum precursor such as diethylaluminum chloride. Alternatively, a suitable gallium precursor may be substituted for the aluminum precursor. The formed doped zinc oxide layer has an Al or Ga dopant concentration of about 2 atomic %.

[0063] Example 11 demonstrates that no thicker doped overcoat ( Fluorine-doped tin oxide) has an adverse effect on the solar performance of the laminated film, because T vis and T sol Both were within target values ≥69% and 41%, respectively. Applicants believe that use of the type of overcoat molded in Example 11 provides lower emissivity and a more neutral color.
Embodiment 12
[0064] Example 12 shows that in addition to SiO 2 bottom layer, such as SnO 2 can be used in the laminated films of the present invention while maintaining a desired degree of T vis and T sol . Examples 13-15 demonstrate that the use of an optional multilayer color suppressing interlayer provides the desired neutral color of transmitted light, while again maintaining a desired degree of T vis and T sol .
[0065] Table 2 presents the results for molded insulating glass (IG) components, the structure of which has been described above. Although the thickness of the doped zinc oxide coating varies significantly, the IG components of the present invention are at or above the desired level, especially T vis ≥62%, Solar Heat Gain Coefficient (SHGC) ≥0.40 and U-value <0.35 consistently demonstrate solar performance. Typically, emissivity is also less than 0.2, and for some embodiments <0.1.
