二氧化鈦奈米漿料的製備與染料敏化太陽能電池的應用

Preparation of TiO2 nanopastes for dye-sensitized solar cells

指導教授 : 蘇昭瑾

摘要


二氧化鈦具有低成本、無毒性及化學穩定性和強氧化力特性等優點,因此大多以二氧化鈦作為半導體材料應用於染料敏化太陽能電池(DSSC)。本篇研究分為兩部分:第一部分為利用水熱法製備溶膠型二氧化鈦,並且製作成溶膠型二氧化鈦漿料,再來將水熱完的溶膠型二氧化鈦經水洗離心後,放置於室溫下自然乾燥以及烘乾得到二氧化鈦粉末,製備成二氧化鈦粉末漿料,最後將溶膠型二氧化鈦漿料與二氧化鈦粉末漿料製備染料敏化太陽能電池的光陽極,並分析光電轉換效率特性。第二部分,將二氧化鈦粉末用醋酸做處理,有助於二氧化鈦奈米顆粒分散在水或乙醇中,減少顆粒之間的團聚情形,最後比較有無酸處理的特性分析。

並列摘要


Titanium dioxide (TiO2) is one of the most commonly used semiconductor materials in dye-sensitized solar cell (DSSC) due to its low cost, nontoxicity, chemical stability, and strong oxidizing power. The focus of this work is twofold. In the first part of this thesis, TiO2 nanosol were prepared by hydrothermal process and the obtained TiO2 nanosol were used to make nano-sol-based paste. The same TiO2 nanosol was dried at room temperature to obtain TiO2 nanoparticles for TiO2 nanoparticle-based paste. The above prepared TiO2 nanoparticles can be further dispersed in water and ethanol by acetic acid treatment. The nano-sol-based and nanoparticle (with and without acetic acid treatment)-based TiO2 paste were used to fabricate the DSSC photoanodes for photo-to-current efficiency study.
