Spacers for insulated glass units
First Claim
1. An insulated glass unit comprising:
- an electrochromic lite comprising a first transparent substrate and layers of an electrochromic device deposited thereon;
the electrochromic lite having a bus bar configured to deliver power to the electrochromic device;
a second lite comprising a second transparent substrate;
a spacer disposed between the electrochromic lite and the second lite;
a sealing material in a first interface between the spacer and the first transparent substrate and in a second interface between the spacer and the second transparent substrate, the sealing material forming a hermetic seal between an interior region of the insulated glass unit and an exterior region outside of the hermetic seal, wherein the interior region is defined by inner surfaces of the first and second transparent substrates and interior faces of the spacer, and the electrochromic device is on a surface of the first transparent substrate facing the interior region; and
a wire passing through the spacer;
the wire making an electrical connection to the bus bar and configured for electrical connection to a power source.

Abstract
This disclosure provides spacers for smart windows. In one aspect, a window assembly includes a first substantially transparent substrate having an optically switchable device on a surface of the first substrate. The optically switchable device includes electrodes. A first electrode of the electrodes has a length about the length of a side of the optically switchable device. The window assembly further includes a second substantially transparent substrate a metal spacer between the first and the second substrates. The metal spacer has a substantially rectangular cross section, with one side of the metal spacer including a recess configured to accommodate the length of the first electrode such that there is no contact between the first electrode and the metal spacer. A primary seal material bonds the first substrate to the metal spacer and bonds the second substrate to the metal spacer.
