Spacers for insulated glass units
First Claim
1. An insulated glass unit (IGU) comprising:
- a. a first substantially transparent substrate having an optically switchable device disposed on a surface of the first substantially transparent substrate;
b. a second substantially transparent substrate;
c. an electrically insulating spacer between the first and the second substantially transparent substrates, the electrically insulating spacer having a substantially rectangular cross section and comprising an electrically insulating material;
d. a sealing material bonding the first and second substantially transparent substrates to the electrically insulating spacer, thereby forming a sealed interior space between the first and second substantially transparent substrates, wherein the optically switchable device faces the sealed interior space of the IGU; and
e. one or more bus bars configured to deliver power to the optically switchable device, wherein the one or more bus bars are disposed, along their length, between the electrically insulating spacer and the first substantially transparent substrate, and not within the inner perimeter of the electrically insulating spacer.

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.
