Abstract
A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments, a sub-oxide layer (e.g., NiCrOx) may be used as a contact layer under an infrared (IR) reflecting layer in order to permit low SF values, high selectivity, and good coloration to be achieved.

43. A method of making a coated article, the method comprising:
-
a) providing a glass substrate;
b) forming a first contact layer comprising an oxide of at least one metal on the glass substrate;
c) forming a layer comprising silver on and in contact with the first contact layer;
d) forming a second contact layer comprising an oxide of at least one metal on and in contact with the layer comprising silver; and
e) wherein steps b) and d) are performed so that the first contact layer is deposited in a manner so as to be less oxided than the second contact layer as deposited and so that the resulting coated article has a selectivity of at least 1.75. - View Dependent Claims (44, 45, 46, 47, 48, 49)
