Abstract: There is provided a smart window having a configuration in which an organic-metallic hybrid polymer and an electrolyte are sandwiched between two sheets of ITO glass; the configuration facilitates an increase in area and, in addition, after the smart window is made transparent by applying drive voltage thereto, it takes time for the smart window to revert to a colored state due to the memory effect thereof even when application of the drive voltage is stopped, and therefore the configuration has excellent power saving properties; and therefore, a smart window system without a power source can be configured by means of combination with a solar cell.
