US Patent 8974864 Method of manufacturing a coated substrate having solar properties

A method of coating a substrate is disclosed. The method includes providing a substrate; depositing an infrared reflecting layer over at least a portion of a substrate; depositing a primer layer over at least a portion of the infrared reflective layer; depositing a dielectric layer over at least a portion of the primer layer; and forming an absorbing layer. The absorbing layer includes an alloy and/or mixture of (a) a metal having an index of refraction at 500 nm less than or equal to 1.0 and (b) a material having a ΔG°f of greater than or equal to −100 at 1000° K. The metal can be silver and the material can be tin.
