Activities to develop thin film variable reflectivity electrochromic windows have focused in five areas in 1991: (1) evaluating the irreversible incorporation of lithium in the counterelectrode material, sputtered indium oxide; (2) responding to evidence that protons substitute for mobile lithium ions in standard'' five-layer electrochromic window structures operating in room air; (3) understanding the electronic and ionic conduction mechanisms in sputtered amorphous lithium niobate, the ion conductor adopted for electrochromic window structures fabricated at Tufts; (4) responding to the discovery that cathodic coloring of the variable reflecting tungsten bronze (Li{sub x}WO{sub 3}) is constrained by interaction with the underlying ITO or SnO{sub 2} transparent conductor in conventional electrochromic window structures; and (5) life testing of electrochromic window prototypes.
