The bus bar can include silver and has a resistivity of at most 6.7×10?6 ?*cm, an average adhesion strength to SiO2 of at least 3N based on 20 measurements, as determined by Method A of ASTM B905-00 (Reapproved 2010), or a classification of at least 4, as determined by Method B of ASTM B905-00 (Reapproved 2010). In another aspect a process of forming an electrochromic device can include forming a transparent conductive oxide layer over a substrate; forming a bus bar precursor over the substrate, wherein the precursor includes silver; and firing the precursor to form a bus bar. Firing can be performed such that the first bus bar is at a temperature of at least 390° C.

  • Patent number: 10421687
    Abstract: A substrate is coated on one face with a thin-films stack having reflection properties in the infrared and/or in solar radiation including at least one metallic functional layer, based on silver or on a metal alloy containing silver, and at least two antireflection coatings. The coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflection coatings. The stack also includes a terminal layer which is the layer of the stack which is furthest from the face. The terminal layer is a metallic layer consisting of zinc and tin, made of SnxZny with a ratio of 0.1?x/y?2.4 and having a physical thickness of between 0.5 nm and 5.0 nm excluding these values, or even between 0.6 nm and 2.7 nm excluding these values.
