隨著化石燃料的日益枯竭，能源危機是人類社會不可忽視的重要課題，替代能源的開發刻不容緩，太陽能的研究即是最受重視的替代能源之一，取之不盡、用之不竭的特性為解決能源危機提供了發展的契機，而染料敏化太陽能電池的開發即是此領域中的一項主流。現行的染料敏化太陽能電池以 N719 為主要的代表，現今的染料開發多以 N3 做為模版來進行官能基團的修飾，藉以提升染料的效能或穩定度。有別於其它染敏電池的研究方向，我們實驗室開發了新型的染料結構 CBTR ，利用全新的結構取代原本的 Bipyridine 做為 Ancillary ligand ，使其相較於 N719 具有更好的效率表現；因此，我們以 CBTR 做為模版，在配位基上增加更多的苯環或噻吩的芳香環來合成 CpPR 與 CtPR ，我們期望可以藉由這樣的結構修飾來提升染料的莫耳消光係數或使其吸收具有較為紅位移的現象以利於紅外光區能量的吸收與利用。藉此來探討增加芳香環對於 Carbene 染料衍生物的影響。 All kinds of every living thing need energy to keep the function well, such as machine, transportation and lighting. However, the fossil fuel’s reserves in the earth is decreasing as time goes by. People should provide a method to solve the energy crisis. In the past years, scientists have discovered that the potential of solar energy. We may solve the energy problem by using or coverting the energy from sunlight. Dye-sensitized of solar cell is one of the applications that scientists use the sunlight. The most typical dyes are N3, N719 and Black dye. Our lab had synthesized a new dye, CBTR, which has the better efficiency than N719 in the same device condition. In my study, we are going to synthesis a series dyes which have more conjugation compared with CBTR. We expect that new dye’s efficiency will be better than CBTR by modifying the structure.
