Abstract:	中文摘要從目前普遍使用火力、水力與核能發電的情形，不難看出人們對於電的依賴是越來越大，由於世界人口數量一直不斷的膨脹而天然資源存量日益減少，加上近年來人們開始對於環保議題的重視，因此，科學家在發展再生能源的同時也不斷的在尋找新的替代能源。其中，太陽光因為供應源源不絕的優點而使的太陽能發電受到科學家們的注意，大家積極的開發與設計新穎的太陽能發電裝置，希望可以更有效率地將太陽光轉換成電。染料敏化太陽能電池中染料的發展自1991年N3染料問世至今已經22年，科學家們不斷地找尋新的官能基(ligand)搭配不同的中心金屬，期望能在電池效率上有重大的突破；本實驗室在2010年發表了以碳烯為官能基，搭配釕金屬為中心的有機金屬染料 - CBTR，經電池元件測試，該染料與N719(目前最常見的標準染料，由Michael Gr?tzel教授及其團隊於1999年所發表)在同樣的Device測試條件下得到較高的電池轉換效率，這也引起了我們對於碳烯官能基的研究興趣，而經過歷年論文期刊的查詢，確認至今亦無任何實驗室對碳烯官能基上取代基的變化對染料的影響；有鑑於此，我們設計一系列染料：CA101、CA102、CA103、CA104，主要是改變碳烯官能基上受體(acceptor)的位置和數目以及改變碳烯官能基與釕金屬反應的實驗條件來得到立體異構物(isomerism)，藉此探討碳烯官能基對於染料敏化太陽能電池的影響。 Abstract Today we primarily use fossil fuels and nuclear energy to heat and power our homes as well as fuel our cars. While we heavily rely on these energy resources for meeting our daily needs, they’re indeed limited on the Earth. We’re using them much more rapidly than they are being created. Eventually, they will run out, and because of the safety concerns and waste disposal problems, renewable energy is becoming a more pressing and the clear choice for future consumer and corporate usage. As such, solar technologies have been gaining its popularity in recent years due to the clean and infinite power of the sun. N3 dye, a dye consists in the dye-sensitized solar cells, was introduced in 1991. Scientists have been trying to discover new functional ligands and central metals to improve the battery efficiency for the past 25 years. In 2010, our lab introduced CBTR, a dye that consist the functional group of carbine and ruthenium as the metal center, outperformed the famous N719 dye in the battery performance. This result obviously intrigued our interest in discovering the potential of using carbine as the functional groups. After conducting a detailed research on past papers, there’s no paper published by any lab on how carbine-ligand can affect the dyes. As such, in this paper, we are going to introduce the synthesis of the NHC carbine-pyridine based ruthenium photosensitizer with different anchoring group, as well as discuss the effect on the device performance. Furthermore, we have designed a series of dyes: CA101, CA102, CA103, and CA104, with the goals to change the numbers and the location of the acceptors on the carbine ligand, and explore the different phases of the functional groups and the acceptors on the influence of the battery.
