1. A vehicle sunroof comprising:
- an electro-optic device forming a variable transmission window comprising;
a first substrate;
a second substrate; and
an electro-optic medium disposed between the first substrate and the second substrate;
a third substrate in connection with the first substrate and formed on an exterior surface of the sunroof;
a first polymer film disposed between the first substrate and the third substrate and laminated to each of the first substrate and the third substrate, wherein the polymer film forms an interlayer film bonded to the first substrate and the third substrate with a lamination material, wherein the polymeric film comprises a polyethylene terephthalate (PET) film laminated to each of the first substrate and the third substrate and the lamination material is of ethylene-vinyl acetate (EVA);
a fourth substrate in connection with the second substrate;
a second polymer film disposed between the second substrate and the fourth substrate and laminated to each of the second substrate and the fourth substrate, wherein the polymer film forms an interlayer film bonded to the first substrate and the third substrate with the lamination material, wherein the polymeric film comprises a polyethylene terephthalate (PET) film laminated to each of the second substrate and the fourth substrate; and
a frame configured to connect the electro-optic device to the vehicle, wherein each of the first substrate, the second substrate, the third substrate, and the fourth substrate are formed of a rigid, impact resistant glass.

Abstract
A vehicle sunroof comprising an electro-optic device is disclosed. The electro-optic device forms a variable transmission window comprising a first layer, a second layer, and an electro-optic medium disposed between the first layer and the second layer. At least one of the first layer and the second layer correspond to a polymeric film. The sunroof further comprises a frame configured to connect the electro-optic device to the vehicle.
