1. An electrochromic structure, comprising:
a substrate;
a first filament in the substrate extending in a direction substantially parallel to a thickness of the substrate;
an electrochromic stack on the substrate, wherein the electrochromic stack comprises:
a transparent conductive layer including a first portion and a second portion spaced apart from the first portion; and
an electrochromic layer disposed over the first portion and the second portion of the transparent conductive layer;
a first bus bar disposed on the first portion of the transparent conductive layer;
a second bus bar disposed on the second portion of the transparent conductive layer, wherein the substrate comprises an edge including a plurality of channels that are spaced apart from one another, wherein at least some of the plurality of channels extend through a thickness of the substrate.
