Solar control glass with optical absorber

Abstract

The invention refers to a glass substrate and a solar control layer stack on at least one face of the glass substrate, the layer stack comprising:—at least one IR-reflective coating (II) comprising a silver containing layer (2′):—at least one absorption coating (IV) comprising an optical absorption layer (4) sandwiched and in direct contact to both between two silicon nitride layers (4′, 4″), the absorption layer (4) consisting of a sub-stoichiometric metal nitride MeNx, a sub-stoichiometric metal oxide MeOy, or a mixture thereof MeNxOy, where Me is at least one of an element from the transition metal group V or/and VI of the periodic system of the elements:—a base coating (I) comprising at least one base layer (1) deposited directly on the substrate, and consisting of a silicon nitride or a metal oxide and thereby forming an inner layer of the solar control stack.
