新型光電致變色智慧節能窗之研究

指導教授 : 陳福榮

摘要


本實驗採用網印法與電鍍法製備光電致變色元件光電電極(二氧化鈦)與電致變色(三氧化鎢)電極,取代昂貴的濺鍍法,並採用聚乙烯醇縮丁醛高分子電解質作為離子傳導層,不僅減少電解質的漏液與揮發,另一方面聚乙烯醇縮丁醛常用於膠合安全玻璃之中間膜,聚乙烯醇縮丁醛與可塑劑混合製膜後,具有高透光性以及優異的黏彈、耐衝撞性質。 本實驗所製備之光電致變色元件褪色與著色時可見光穿透度分別為50%和16%、太陽熱能穿透度為52%和7%,已符合建築使用上光學操作範圍,在長效方面,元件於60天時效後約保有原本72%可見光變色範圍與85%太陽熱能調節範圍。此外,在落球衝擊測試中,光電致變色元件可藉由聚乙烯醇縮丁醛膠態電解質(PVB-electrolyte)吸收並分散衝擊力,成功的避免了衝擊時玻璃破碎飛濺的發生,因此,本實驗成功的製作出同時具有低成本、長效穩定性以及具有安全性的光電致變色元件,未來可全面應用於建築與汽車上。

Photoelectrochromic cells fabricated with titanium photo-electrode prepared by screen printing, tungsten trioxide electrochromic electrode prepared by electrodeposition and laminated by a Polyvinyl butyral polymer based ion conductor are introduced in this study. The fabricated processes save lots of equipment cost compare to sputter process. Polyvinyl butyral quasi-solid electrolytes reduce the solvent leakage, volatilities and provide excellent optical and physical properties such as high transmittance, elasticity and impact-resistance. The visible transmittance of the quasi-solid PEC device is varied between 50% (bleached state) and 16% (coloured state). On the other hand, the solar radiation transmittance is varied between between 52% and 7%. After 60 days, the PEC device maintain 72% visible transmittance range and 85% solar radiation transmittance range, respectively. In falling ball impact testing, the interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the steel ball completely pierce the glass.
