Abstract
Example embodiments of this invention relate to a method of making a thermally tempered coated article including a transparent conductive oxide (TCO) film in a color compression configuration supported by a tempered glass substrate. A coated article, that is thermally tempered and made by such a process, is also provided. Coated articles according to certain example non-limiting embodiments of this invention may be used in applications such as solar cells, oven doors, electrostatic discharge glass, solar control windows, defrosting windows, or other types of windows in certain example instances.
Claims22
A method of making a thermally tempered coated article including a transparent conductive film on a tempered glass substrate, the method comprising:
- providing a glass substrate;
- sputter-depositing a high index layer having a high refractive index on the glass substrate, and then sputter-depositing a low index layer having a low refractive index on the glass substrate over at least the high index layer;
- after the high index layer and the low index layer have been sputter-deposited on the glass substrate, sputter-depositing an amorphous film on the glass substrate over each of the high index layer and the low index layer;
- thermally tempering the glass substrate with the amorphous film, the low index layer, and the high index layer thereon;
- and
- wherein heat used in said tempering causes at least the amorphous film to transform into a crystalline film, and wherein the crystalline film is transparent to visible light and electrically conductive following said tempering.
A method of making a thermally tempered coated article including a transparent conductive film on a tempered glass substrate, the method comprising:
- providing a glass substrate;
- forming a high index layer having a high refractive index on the glass substrate, and a low index layer having a low refractive index on the glass substrate over at least the high index layer;
- after the high index layer and the low index layer have been formed, forming an amorphous film comprising a metal oxide on the glass substrate over each of the high index layer and the low index layer;
- thermally tempering the glass substrate with the amorphous film, the low index layer, and the high index layer thereon;
- and
- wherein heat used in said tempering causes at least the amorphous film to transform into a film which is substantially transparent and electrically conductive.
