Abstract:	本研究係以刮刀成膜法進行二氧化鈦薄膜製備，將二氧化鈦薄膜燒結於FTO導電玻璃，製成多孔性薄膜電極。實驗中探討二氧化鈦薄膜電極於製備過程中，探討於分散劑、燒結溫度、燒結時間及膜厚等實驗參數進行實驗，搭配染料(黑莓)及電解質(0.5M KI + 0.05I2加入混合於乙基乙二醇)，探討其對染料敏化太陽能電池效率之影響。實驗特性分析，以FESEM觀察二氧化鈦薄膜層之整體結構、顆粒呈現；以3D表面輪廓儀量測其薄膜厚度；以UV-Vis分析染料(黑莓)之吸收特性。藉由分散劑之實驗，因使用醋酸時可制止二氧化鈦表面粒子產生聚集現象，於濃度0.1M之醋酸下，可得到較佳之光電轉換效率；藉由燒結時間之實驗，結果呈現，因溫度較高(約大於450℃)可將有機物質完全去除，本研究得到於550℃/30min下，可得較佳之轉換效率；於3D表面輪廓儀量測之二氧化鈦膜厚為18μm。 In this study the manufacture and the performance evaluation of dye sensitized solar cell(DSSC) are performed. This study focuses on how preparation parameters of titanium dioxide thin film affect the performance of DSSC. In the study, the a blackberry was used as dye and 0.5M KI ,0.05I2 in ethyl glycol was used as electrolyte. The titanium dioxide thin film was made by doctor blade method. The mesoporous titanium dioxide thin film was sintering on FTO glass. The titanium dioxide thin film electrode preparation includes the dispersant used, sintering temperature and sintering time. The film thickness and morphological properties were measured to relate various film manufacture parameters with DSSC performance. Among three dispersants of sulfuric acid, nitric acid and the acetic acid, the acetic acid was found to be adsorbed more on the surface of titanium dioxide that prohibits individual particle from aggregation as revealed in SEM measurements. Hence the acetic acid was selected as dispersants for the rest tests. An averaged 18μm film thickness was measured by 3D surface profiler. The test concludes that the optimal parameters in the titanium dioxide thin film manufacturing to obtain best DSSC performance are 0.1M concentration of acetic acid s dispersant, the sintering temperature 550℃ for 30min. The higher temperature in the sintering process is believed to burn out more organic matter in the titanium dioxide pore that enhance the exposure of the film to solar radiation, hence more optical-electro transfer improves the DSSC performance.
