Abstract
This disclosure provides configurations, methods of use, and methods of fabrication for a bus bar of an optically switchable device. In one aspect, an apparatus includes a substrate and an optically switchable device disposed on a surface of the substrate. The optically switchable device has a perimeter with at least one corner including a first side, a second side, and a first vertex joining the first side and the second side. A first bus bar and a second bus bar are affixed to the optically switchable device and configured to deliver current and/or voltage for driving switching of the device. The first bus bar is proximate to the corner and includes a first arm and a second arm having a configuration that substantially follows the shape of the first side, the first vertex, and the second side of the corner.
Claims (21)
1 . An electrochromic device comprising:
a substrate that 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 layer, wherein:
the first bus bar has a first segment with a first section and a second section, and a second segment with a third section and a fourth section,
the first section and the third section are along the first side,
a gap exists between the first section and the third section,
the second section is along the third side,
the fourth section is along the fourth side of the substrate, and
the first bus bar having no section along the second side;
a second bus bar electrically connected to a second transparent conductor layer, wherein:
the second bus bar has a third segment with a fifth section and a sixth section, and a fourth segment with a seventh section and an eighth section,
the fifth section and the seventh section are along the second side,
a second gap exists between the fifth section and the seventh section,
the sixth section is along the third side,
the eighth section is along the fourth side, and
the second bus bar having no section along the first side; and
a first voltage supply terminal electrically connected to the first segment and/or the second segment of the first bus bar.
2 . The electrochromic device of claim 1 , further comprising:
an electrochromic stack between the first transparent conductor layer and the second transparent conductor layer.
3 . The electrochromic device of claim 1 , wherein the first bus bar and the second bus bar are diagonally opposed.
4 . The electrochromic device of claim 1 , wherein a same voltage is applied to the first segment and the second segment of the first bus bar, and the same voltage is applied to the third segment and the fourth segment of the second bus bar.
