本論文的目的是在玻璃基板上以超臨界二氧化碳製程形成多孔銻摻雜二氧化錫(ATO)電極及其在銀沉積技術上的應用。
製程是自旋塗佈一層陰極ATO奈米粒子溶液於銦錫氧化物(ITO)玻璃上，厚度為1.4μm，在溫度條件為60 oC下使用超臨界形成的陰極多孔隙結構。在兩電極之間封入一層0.08M濃度的電解液(由碘化銀、碘化納及二甲基亞砜所組成)而形成的一種類似“三明治”的結構。元件製程後，在背面噴上白色的漆。當在施加電壓的時候，電化學反應使溶解在電解質中的銀離子還原為銀而析出在透明電極上，看起來是黑色的；反之，如果把析出的銀溶解到電解液中，由於直接看到的是透明的電解液，所以會看到背面所噴上的白漆。
由於陰極多孔銻摻雜二氧化錫(ATO)薄膜很薄，因此在氧化過程中是透明的。在1V的驅動電壓下，電流飽和密度為3.1 mA/cm2。 0.5cm乘0.5cm大小的元件量測結果，對比度為1:4.4；反應時間則為3.7秒。

Porous antimony-doped tin oxide (ATO) cathodes formed by supercritical CO2 (SCCO2) treatment for silver electro-deposition devices were proposed.
The porous ATO cathode with a thickness of 1.4μm was formed by coating the nano-particle ATO solution on ITO glass. The porous structure of the cathodes was obtained by applying SCCO2 treatment at 60oC on the spin-coated ATO thin films. A layer of electrolyte(formed by AgI, NaI and DMSO)was enclosed by two electrodes to to form a so-called“sandwich” structure. After the fabrication process, white paint was spray on the back side of the glass substrate. Due to the thickness of the ATO cathode, the cathode is observed to be transparent during the oxidation process. The Black state of the device was observed during the reduction of silver molecules which were anchored onto the surface of the 1.4μm thick ATO cathode.
The average transmission contrast ratio of 4.4 was obtained in visible spectrum at a driving voltage of 1V and a saturation current density of 3.1 mA/cm2. In addition to that, 0.5 cm by 0.5 cm device with 65μm cell gap and 0.08 M electrolyte concentration, an electrochromic switching time of 3.7 seconds was achieved .
