Abstract
Certain example embodiments relate to electric, potentially-driven shades usable with insulating glass (IG) units, IG units including such shades, and/or associated methods. In such a unit, a dynamic shade is located between the substrates defining the IG unit, and is movable between retracted and extended positions. The dynamic shade includes on-glass layers including a transparent conductor and an insulator or dielectric film, as well as a shutter. The shutter includes a resilient polymer, a conductor, and optional ink. Holes, invisible to the naked eye, may be formed in the polymer. Those holes may be sized, shaped, and arranged to promote summertime solar energy reflection and wintertime solar energy transmission. The conductor may be transparent or opaque. When the conductor is reflective, overcoat layers may be provided to help reduce internal reflection. The polymer may be capable of surviving high-temperature environments and may be colored in some instances.
