Abstract
本研究以純度鈦箔片(99.7%)為陽極，白金(Pt)為陰極，於乙二醇(Ethylene Glycol, EG)、氟化銨(Ammonium Fluoride, NH4F)及去離子水(Deionized water, DI)為電解液，以定電壓之陽極處理方式，製備出二氧化鈦奈米管，期助於染料敏化太陽電池的效率提昇。
使用染料為N719，入射光強度為100 mW/cm2情況下，當管長為30 μm時，測量出最高的光電轉換效率，其短路電流Jsc為11.30 mA/cm2、開路電壓Voc為0.71 V、填充因子FF為0.48、轉換效率η為3.92%。
In the study, TiO2 nanotube was manufactured by anodization with electrolyte of mixed solution of ethylene glycol (EG), ammonium fluoride (NH4F) and DI water, high purity titanium (99.7%) as anode and platinum as cathode, dye-sensitized solar cells contribute to efficiency. By sensitizing the anode with N719 dye and exposing under a light which light intensity is 100 mW/cm2, the length for 30 μm which measured by the highest photoelectric conversion efficiency, the Jsc = 11.30 mA/cm2, Voc = 0.71 V, FF = 0.48, η = 3.92%.
