Abstract
An electro-optic element includes a first electroactive film including a first electroactive component sequestered adjacent to a first electrically conductive layer and a second electroactive film including a second electroactive component sequestered adjacent to a second electrically conductive layer. At least one of the first electroactive film and the second electroactive film is capable of reversibly attenuating transmittance of light having a wavelength within a predetermined wavelength range. The first electroactive component can include a first oxidation state and at least a second oxidation state. An amount of the first electroactive component relative to the second electroactive component can be configured to limit formation of the second oxidation state of the first electroactive component.
