MULTIPLE CONTROLLED ELECTROCHROMIC DEVICES FOR VISIBLE AND IR MODULATION

摘要

An electrochromic device (ECD) includes an electrochromic cell and, optionally, one or more additional electrochromic cells where all cells are parallel, and where at least one of the electrodes of one of the cells comprises a single-walled carbon nanotube (SWNT) film The electrochromic cells allow the control of transmittance of two or more different portions of the electro-magnetic spectrum through the ECD. One cell can control the transmittance of visible radiation while the other cell can control the transmittance of IR radiation. The ECD can be employed as a“smart window”to control the heat and light transmission through the window. The ECD can be in the form of a laminate that can be added to an existing window.
