本研究針對白金軟板(ITO/PEN)對電極在可撓式染料敏化太陽能電池中所扮演的角色進行有系統的分析，以目前最常見的三種技術：化學還原、電鍍、濺鍍進行討論。本實驗著重在電鍍方面，因其具備了能控制白金顆粒的變化、快速製備、和減少浪費等優點，在分析方面，除了進行電池元件的量測以外，還包含SEM照片的拍攝、電池阻抗的量測、在硫酸溶液和碘溶液進行CV測試，以及白金含量的分析等等；其中，本研究也建立了電鍍理論相關的機制並引進兩階段式的電鍍方法，在六氯鉑酸中，以先鍍著小顆粒但密度高的白金顆粒在基板上後，在長時間的鍍著較大顆粒的白金離子，藉由調整電鍍參數的電位、時間、圈數，並與前述分析相互對應，得到在-0.35V電鍍3秒至0.2V電鍍0.5秒時重複100迴圈時，可以得到最佳催化能力、最高的白金顆粒表面積和元件效率：藉由這一系列對應對電極的分析，推論出白金顆粒的表面積和元件的Jsc及白金催化能力成正比，而對電極的片電阻和白金顆粒的阻抗也和元件的FF相互呼應。
優化過的電鍍白金ITO/PEN對電極與以自製24wt%二氧化鈦漿料，搭配膠化的碘電解液系統，在100mW/cm2的光強度下，得到最高為7.11%的光電轉換效率，而將對電極基板換成鈦金屬並進行相同的優化過程後，可得到最高7.305%的光電轉換效率。

This study investigated the characteristics of platinum (Pt) catalyst layers having a nanoflowers structure, deposited by electrodeposition (ED) on conductive indium-doped tin oxide coated polyethylene naphthalate (ITO-PEN) for flexible dye sensitized solar cells (DSSCs). The scanning electron microscope (SEM) images energy dispersive spectroscopy (EDS), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS) response have evidenced the comparison of the catalytic activities of these counter electrodes (CEs) and surface area of Pt for the reduction of tri-iodide to iodide. Two-step pulse electrodeposited technique make CE have high surface area of Pt.
These results demonstrate that the flexible DSSCs using electrodeposited Pt on the ITO-PEN surface facilitates the electronic transport properties in catalytic reaction to enhance the efficiency and catalytic activity. The flexible DSSCs based on ITO-PEN CEs in conjunction with a AN-based nanocomposite gel electrolyte has achieved the highest solar cell conversion efficiency of 7.11% under one sun illumination (AM1.5, 100 mW cm−2).
