摘要

本研究採用水熱法以及刮刀塗佈法在ITO基板上製作氧化鋅奈米柱以及二氧化鈦薄膜當工作電極應用於染料敏化太陽能電池。
使用磁控濺鍍沉積ZnO晶種層在ITO基板上以及使用旋轉塗佈法旋塗單層奈米球，以酸性溶液來蝕刻未黏附奈米球之晶種層區域，留下奈米球下之ZnO晶種層。使用水熱法以不同的生長時間成長氧化鋅奈米柱，在以旋塗單層奈米球來控制氧化鋅奈米柱生長範圍，將二氧化鈦奈米粒子結合氧化鋅奈米柱製備複合式工作電極。
將複合式工作電極經過退火後浸泡於染料中，之後與Pt背電極進行封裝，最後再注入電解液已完成染料敏化太陽能電池之封裝，進行量測與分析染料敏化太陽能電池之效率。

In this study, ZnO nanorods and TiO2 film working electrodes were prepared on ITO substrates by hydrothermal method and doctor blade method in dye sensitized solar cell. We have deposited ZnO seed layer on ITO substrate by radio frequency magnetron sputter, then monolayer of nanospheres were spin coating on ZnO seed layer. After that, we used the acidic solution to etch non-adherent nanospheres area within the seed layer before nanospheres layer was removed from the sample. ZnO nanorods were grown on selection area ZnO seed layer by hydrothermal method with different time. Finally, TiO2 nanoparticles were cover in ZnO nanorods as composite working electrode by doctor blade method. The samples were soaked in dye after annealed, encapsulated with Pt back electrode to prepare the dye-sensitized solar cell, so that we can measured the cell efficiency.
