摘要：由於電致色變窗戶無論在商業大樓、一般住宅或是汽車、航空器等交通工具皆極富節能應用價值與商業潛力，本研究計畫自民國96年1月1日開始以兩年時程進行應用奈米結構鐵氰化銦（InHCF）為輔助電極之新型高節能效率電致色變窗戶系統開發。使用InHCF透明輔助電極時，工作電極不必預先著色，可減少窗戶元件封裝難度並有效地提升系統操作穩定性；另一方面，InHCF為相對新穎之材料，所開發出之節能窗戶系統將極富專利優勢。根據96年度InHCF新元件系統平行開發與全光譜調幅性能評估結果，我們發現以WO3為工作電極、奈米InHCF為輔助電極並搭配非水溶液電解質的元件組合具有良好的節能效果與製成智慧型窗戶元件的可能性。因此，為縮短WO3-InHCF元件成為實用之新型高節能效率電致色變窗戶商品，97年度的計畫目標將鎖定下列兩大關鍵技術 –「元件操作穩定性提升」與「InHCF奈米鍍膜製程大型化」進行研究。在「元件操作穩定性提升」方面，我們將由「非水溶液複方電解質研究」及「強化奈米結構InHCF鍍膜研究」兩大方向著手；在「InHCF奈米鍍膜製程大型化」方面，則將分別嘗試「電鍍」、「網印」及「浸鍍」等三種製程探究大尺寸奈米InHCF鍍膜的成功要訣。我們冀望藉由新年度計畫的執行，勾勒出奈米InHCF透明輔助電極在新型變色節能窗戶應用上之發展技術路程圖。
Abstract: Since electrochromic windows (ECWs) for intelligent daylighting control are of great value for both energy-saving and decoration applications in commercial buildings, ordinary housing, automobiles, aircrafts, and so on, we proposed a two-year energy tech plan (2007-2008) to develop novel, viable ECW systems using a nanostructured indium hexacyanoferrate (InHCF) counter electrode. When using a transparent InHCF counter electrode, the working electrode does not need precoloration during device assembly. Hence, the assembly can be simplified, and system stability can be enhanced accordingly. Besides, the ECW systems developed by this project will be advantageous for the patent application, because InHCF is a relatively new material. According to our findings in year 2007, WO3 is the most promising working electrode candidate among six electrochromic materials tested for InHCF-based smart window applications, and we also found that non-aqueous electrolytes should be used to achieve long cycle life. To put WO3-InHCF ECWs into practice in the visible future, the project goals in year 2008 will focus on (1) the enhancement of device stability, and (2) the scaling up of nano-InHCF coating. The enhancement of device stability will be done by optimization of a complex non-aqueous electrolyte and reinforcement of InHCF coating’s nanostructures. The scaling up of nano- InHCF coating will be attempted by electrodeposition, screen printing, and dip coating, respectively. We expect to provide a useful roadmap for developing novel, commercially viable ECWs based on nano-InHCF counter electrodes from the outcome of this project.
