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.電致色變鐵氰化銦奈米結構智慧型窗戶三氧化鎢electrochromicindium hexacyanoferrate (InHCF)nanostructuredsmart windowstungsten oxide
