Abstract
An electrochromic apparatus is disclosed. The electrochromic device can include a first bus bar electrically connected to a first transparent conductor, where the first bus bar comprises a first segment between a second segment and a third segment, where the first segment has a first thickness that is less than a second thickness of the second segment and less than a third thickness of the third segment. The electrochromic apparatus can further include a first voltage supply terminal that is offset from a center of the first bus bar.
Claims20
An electrochromic device comprising:
- a first bus bar electrically connected to a first transparent conductor, wherein the first bus bar comprises a first segment between a second segment and a third segment, wherein the first segment has a first thickness that is less than a second thickness of the second segment and less than a third thickness of the third segment.
An electrochromic device comprising:
- a substrate comprises a first side, a second side, a third side, and a fourth side, wherein the first side is opposite to the second side, wherein the third side is orthogonal to the first side, and wherein the fourth side is opposite the third side;
- a first bus bar electrically connected to a first transparent conductor, wherein the first bus bar has a major length along the first side of the substrate and at least one minor length along the third side of the substrate;
- and
- a first voltage supply terminal connected to the first bus bar along the major length of the first bus bar, wherein the voltage supply terminal is offset from a center of the major length of the first bus bar.
An electrochromic device comprising:
- a substrate comprises a first side, a second side, a third side, and a fourth side, wherein the first side is opposite to the second side, wherein the third side is orthogonal to the first side, and wherein the fourth side is opposite the third side;
- a first bus bar electrically connected to a first transparent conductor, wherein the first bus bar comprises a first segment with a first length, a second segment with a second length, and a third segment with a third length, wherein the first segment is along the first side of the substrate, the second segment is along the third side of the substrate, and the third segment is along the fourth side of the substrate;
- and
- a second bus bar electrically connected to a second transparent conductor, wherein the second bus bar comprises a fourth segment with a fourth length, a fifth segment with a fifth length, and a sixth segment with a sixth length, wherein the fourth segment is along the second side of the substrate, the fifth segment is along the third side of the substrate, and the sixth segment is along the fourth side of the substrate, and wherein the second segment is closer to the fourth side than the fifth segment.
