There is currently world-wide interest in developing practical electrochromic smart windows. This is because the use of such windows could have significant impact on making buildings more energy efficient, and therefore could significantly influence the world's economy and international policies. This is especially important since more than 1/3 of the energy consumed in the US is used to control the climate of buildings. The Tufts research program has focused on theoretically and experimentally: identifying, designing, depositing, and evaluating thin film materials as individual layers and in multilayer window device structures. The current window device design is based on electrically varying the reflectivity of a EC (electrochromic) layer in a 5-layer structure: (TC(=ITO)/vert bar/EC (=C-WO/sub 3/)/vert bar/IC (= a /minus/ LNO)/vert bar/ CE (=In/sub 2/O/sub 3/)/vert bar/TC (=ITO)); where TC = transparent conducting layer, ITO = tin-doped indium oxide, c /minus/ WO/sub 3/ = (poly)crystalline tungsten trioxide, IC = ion conducting layer, a /minus/ LNO = amorphous lithium niobate, and CE = counterelectrode layer. 4 refs.
