染料敏化太陽能電池與超級電容之整合型元件之研究

本研究以摻雜木質活性碳與氧化鋅奈米粒子製備複合型超級電容之碳電極並與染料敏化太陽能電池進行整合成為綜合能源系統，並探討兩者特性與影響。利用濾紙過濾，以烘烤方法製作出具有氧化鋅奈米粒子披覆木質活性碳之結構碳粉，並製作出超級電容複合式電極，並透過改變木質活性碳的重量來找出最佳電容特性之複合式碳電極製備參數。另外利用刮刀塗佈法增加二氧化鈦薄膜厚度，薄膜厚度的增加，染料吸附量也就越多，照光後染料激發之電子增多，並有效提升染料敏化太陽能電池的效率。以循環伏安(CV)和恆電流充放電測試(Charge-discharge test)探討超級電容之電極影響；以太陽能模擬器(Solar Simulator)測量染料敏化太陽能電池整體的光電流轉換效率；利用場發射掃描式電子顯微鏡(FE-SEM)觀察複合式碳電極與二氧化鈦電極表面之結構。研究結果顯示，添加2g的木質活性碳與25μm隔離膜可製備出最佳電容特性之複合式碳電極，其加入水系電解質(1M KOH)比電容值為265.93 F/g，其充放電效率可達到81%，染料敏化太陽能電池光電轉換效率6.5%，並將多組整合元件進行串並聯成功驅動LED，完成了在一個元件進行能量轉換與能量儲存。

In this study, the carbon electrode of composite supercapacitor was prepared by using mixed zinc oxide nanoparticles and wood activated carbon, and integrated with dye-sensitized solar cells to become integrated energy system, and the characteristics and influence were discussed. Using the filter paper to filter, to bake the method to produce a zinc oxide nano-particles coated with wood activated carbon structural carbon powder, and to produce a super capacitor composite electrode, and by changing the weight of wood activated carbon to find the best capacitance characteristics of the Preparation of Composite Carbon Electrode. In addition, the use of scraper coating method to increase the thickness of titanium dioxide film, film thickness increases, the more the amount of dye adsorption, after the dye to stimulate the electrons increased, and effectively enhance the efficiency of dye-sensitive solar cells. The results show that the addition of 2g of wood activated carbon and 25 μm separator can produce the best capacitance of the composite carbon electrode, the addition of water electrolytes (1M KOH) than the capacitance value of 265.93 F / g, the charge and discharge efficiency of up to 81%, the dye Sensitized solar cell photoelectric conversion efficiency of 6.5%, and multiple sets of integrated components for serial and parallel drive LED.
