生活處處皆須要能源，但是傳統能源的使用會產生溫室氣體排放或是產生核廢料而造成環境的汙染，加上天然資源的有限，開發或找尋替代能源為必須首要任務，眾多替代能源中太陽能被認為是乾淨並且不會斷絕的能源。 傳統單晶矽太陽能電池製造成本較高，薄膜電池部分原料為有毒物質，而染料敏化太陽能電池則是利用便宜的元件、簡單的製程，雖然其光電轉換效率尚未達到其他二者，但是其發展的前景仍是備受期待。 光敏染料是染料敏化太陽能電池中重要的元件，在光敏染料釕金屬錯合物中引進氮雜環碳烯(N-heterocyclic carbene)單元並延長其共振結構，藉其特殊σ donor特性與對可見光區高莫耳消光系數，希望能有效將太陽光能轉換成電能。 本論文成功合成含有多共振結構釕金屬錯合物應用於光敏染料，之後將會把光敏染料分子製作成元件並進行光電轉換之測試。 Life needs energy everywhere. However, the use of the traditional energy will produce the greenhouse gas to discharge or the nuclear waste material which causes the environmental pollution. In addition, natural resources are limited. Development or looking for alternative energy source must be with primary task. The solar energy is considered to be the clean and sustainable energy in numerous alternative energy source. Single-crystal silicon solar cells’ manufacturing cost is relatively high. Thin-film solar cells which some raw materials are noxious substances. The dye-sensitized solar cells utilize cheap component and simple process. Though its conversion efficiency has not reached other two yet. But the prospect of its development is still expected. The photosensitizers are important components in the dye-sensitized solar cells. Introduce the unit of the N-heterocyclic carbene in photosensitizers ruthenium complex and extend its conjugated structure. By using its σ donor characteristic and higher visible light molar extinction coefficient hope that solar energy can be converted into electrical energy. This thesis succeeds in synthesis of a ruthenium complex containing highly conjugated branches. We will make into the components and proceed into the photoelectric conversion test.
