    Abstract: As the cost of energy has increased, the use of solar coatings on automotive and architectural glazing has enjoyed massive growth. Most solar coatings have metallic silver layers that are highly reflective in the infrared. The silver is deposited over a “wetting” layer which must have a certain level of roughness to prevent agglomeration of the silver and to ensure good adhesion. However, a very smooth wetting layer is beneficial in minimizing haze and improving solar performance. These competing factors make it difficult to deposit a silver layer that promotes both high stability and good adhesion as well as excellent optical and solar properties. The disclosure uses an AgAl/Ag bilayer, which transitions in the composition from silver-aluminum to silver. The bilayer has excellent stability and does not require a rough substrate, thus enabling the use of a smooth high-aluminum-content ZnAlOx wetting layer in providing a coating with superior stability, adhesion, optical, and solar characteristics.
