An insulating glass unit, comprising: first and second substrates, each having interior and exterior major surfaces, the interior major surface of the first substrate facing the interior major surface of the second substrate; a spacer system for helping to maintain the first and second substrates in substantially parallel spaced apart relation to one another and to define a gap therebetween; and a dynamically controllable shade (202a, 202b) interposed between the first and second substrates, the shade (202a, 202b) including: a first conductive film provided, directly or indirectly, on the interior major surface of the first substrate; a dielectric or insulator film provided, directly or indirectly, on the first conductive film; and a shutter including a polymer material supporting a second conductive film, the polymer material being extendible to serve as a shutter closed position and retractable to serve a shutter open position, wherein an upper surface of the second conductive film is roughened and/or textured to contribute to a reduction in total reflection from the shutter and/or to promote diffuse reflection, compared a shutter having a second conductive film that is not correspondingly roughened and/or textured, the upper surface of the second conductive film facing away from the polymer material; and wherein the first and second conductive films are configured to be electrically connectable to a power source that is controllable to selectively set up an electric potential difference to correspondingly drive the polymer material between the shutter open and closed positions. first and second substrates, each having interior and exterior major surfaces, the interior major surface of the first substrate facing the interior major surface of the second substrate; a spacer system for helping to maintain the first and second substrates in substantially parallel spaced apart relation to one another and to define a gap therebetween; and a dynamically controllable shade (202a, 202b) interposed between the first and second substrates, the shade (202a, 202b) including: a first conductive film provided, directly or indirectly, on the interior major surface of the first substrate; a dielectric or insulator film provided, directly or indirectly, on the first conductive film; and a shutter including a polymer material supporting a second conductive film, the polymer material being extendible to serve as a shutter closed position and retractable to serve a shutter open position, wherein an upper surface of the second conductive film is roughened and/or textured to contribute to a reduction in total reflection from the shutter and/or to promote diffuse reflection, compared a shutter having a second conductive film that is not correspondingly roughened and/or textured, the upper surface of the second conductive film facing away from the polymer material; and a first conductive film provided, directly or indirectly, on the interior major surface of the first substrate; a dielectric or insulator film provided, directly or indirectly, on the first conductive film; and a shutter including a polymer material supporting a second conductive film, the polymer material being extendible to serve as a shutter closed position and retractable to serve a shutter open position, wherein an upper surface of the second conductive film is roughened and/or textured to contribute to a reduction in total reflection from the shutter and/or to promote diffuse reflection, compared a shutter having a second conductive film that is not correspondingly roughened and/or textured, the upper surface of the second conductive film facing away from the polymer material; and wherein the first and second conductive films are configured to be electrically connectable to a power source that is controllable to selectively set up an electric potential difference to correspondingly drive the polymer material between the shutter open and closed positions.
