本論文主要目的為研究不同的三牙配位基取代染料硫氰根後，應用於固態電池的效率及光照穩定性之分析。本研究選用具有良好效率表現及穩定性的Z907染料，以及四種不同的無硫氰根染敏分子(Thiocyanate-free Ruthenium sensitizers ,TFRS)，分別為Jou-2186、Jou-2191、Pei-1115、Pei-1094，將五種染料應用於固態染敏系統並分析其電性表現。TFRS受限於本身結構易堆疊，因此需要添加共吸附劑，但此舉又會抑制染料吸附量，因此需在兩相反趨勢間取得效率最佳值。利用小分子酸後處理修飾TiO2表面空隙，以及加入p型參雜使Spiro部分氧化後，可使Jou-2186元件效率達3.2%，接近Z907元件3.5%的效率表現。TFRS和Z907經光照測試後，亦證實了Z907的光照穩定性無論在開放式光劣化測試或封閉式光照穩定系統中皆比TFRS弱，顯示硫氰根的取代確實助於提升元件光照穩定度。

In this study, we investigated the photovoltaic performances and light soaking stability of thiocyanate-free Ruthenium(II) sensitizers(TFRS) for solid-state dye sensitized solar cell. The photovoltaic performance for Z907 dye was better than TFRS, with higher dye adsorption amount and longer electron lifetime. After light soaking aging, TFRS showed better light soaking stability to Z907. The result indicated that replacing the thiocyanate ligand could help increasing light soaking stability.
