Electro-optic element electrical connections

An electro-optic element comprising:

• a first substrate being substantially transparent and having a first surface, a second surface, and a first peripheral edge;
• a second substrate substantially parallel the first substrate, the second substrate having a third surface, a fourth surface, and a second peripheral edge;
• a first electrode associated with the second surface;
• a second electrode associated with the third surface;
• an electro-optic medium disposed between the first electrode and the second electrode;
• a groove defined by at least one of a first groove surface and a second groove surface, the first groove surface being substantially flat and extending between the second surface and at least one of the first peripheral edge and the first surface at a non-orthogonal angle, the second groove surface being substantially flat and extending between the third surface and at least one of the second peripheral edge and the fourth surface at a non-orthogonal angle;
• and
• a first electrical bus disposed, at least in part, in the groove, the first electrical bus electrically connected to the first electrode;
• and
• a second electrical bus disposed, at least in part, in the groove, the second electrical bus electrically connected to the second electrode.
