1. A solar absorbing-reflective film, comprising:
a flexible infrared (IR) reflective transparent conductive film (20) comprising a single layer of a single material;
a flexible transparent conductive film (30) comprising a single layer of a single material;
at least one layer of liquid crystal dispersion located between said flexible IR reflective transparent conductive film and said flexible transparent conductive film (10), said liquid crystal dispersion comprising metal-organic mesogen dye compositions; and,
at least one electrical contact in communication with said flexible transparent conductive film;
wherein:
said liquid crystal dispersion comprises at least one liquid crystal mixture selected from the group consisting of:
a cholesteric liquid crystal mixture characterized by broad-band wavelength reflecting capabilities;
a cholesteric liquid crystal mixture characterized by a broad-band wavelength reflecting capability characterized by a pitch in an IR region; and,
chiral nematic mixtures of liquid crystal in said liquid crystal dispersion adapted to behave as a broadband cholesteric phase; and,
said at least one liquid crystal mixture is configured to allow IR reflection of said solar absorbing-reflective film to be dynamically controlled by an amount of electric field applied.
