    Abstract: 具光照調控與熱輻射調節功能之智慧型窗戶,於未來建築節能減碳方面的應用相當 重要。光電致色變元件能夠自動因應外界光照變化,或依據使用者的操作而調節對於入 射光之吸收度,在此方面的應用具有很大的發展潛力。本二年期計劃將致力於開發具有 光電致色變性質之新型三氧化鎢/氧化鈦奈米複合材料薄膜,使用此薄膜組裝光電致色 變元件,並對薄膜與元件之效能進行評估與最佳化。計畫第一年的目的為製備三氧化鎢 /氧化鈦奈米複合材料薄膜,並最佳化其光電致色變效能。研究的主要重點包括薄膜之 製程開發、成分結構分析以及光電化學反應特性量測與機制探討,以取得薄膜最佳之製 備條件參數。計畫第二年將承接第一年之研究成果,以組裝光電致色變元件並最佳化其 效能為執行目標。計畫先進行小尺寸元件之組裝技術開發、效能評估與最佳化,然後應 用所得之結果與經驗,發展大面積之光電致色變元件。元件之穿透率調幅、著色效率、 著色/去色應答時間與均勻度以及循環操作壽命,為評估元件光電致色變效能的主要指 標。
    Photoelectrochromic (PEC) devices change their light-absorption abilities in response to the variations of ambient light conditions as well as the externally applied bias, and find their potential applications as smart windows to control the amount of light and heat passing through, which can save costs for air-conditioning and lighting in buildings. The present two-year project will dedicate in the developments of new tungsten trioxide/titanium oxide nanocomposite thin films with PEC properties, and construct PEC devices based on these nanocomposite materials. The major goals of the first-year project is to develop the synthesis procedures for the tungsten trioxide/titanium oxide nanocomposite thin films, then analyze and optimize their PEC performances. With the results and experiences from the first-year in hand, the second-year project will focus on the fabrication and the performance optimization of the PEC devices with large working areas. The major performance indexes for a PEC device including coloring/bleaching transmittance change and uniformity, response time, coloration efficiency and cycle life.
