ABSTRACT:
A self-contained sun sensitive window made up of liquid nematic crystals sandwiched between two transparent conductors is powered directly by a solar cell. An increase in light intensity upon the solar cell reduces the transparency of the window, resulting in a constant intensity behind the window.
