為了解決世界能源危機，乾淨無汙染的再生能源便是目前世界引頸期盼的目標，而其中最不會受到地形、環境限制的再生能源便是太陽能電池的發展，而目前以含有釕 (Ru) 金屬的染料敏化太陽能電池擁有最好的轉化效率，但是因為其來源稀少，製作成本也相對提高，才開始有了不須昂貴的釕 (Ru) 金屬也可以合成出太陽能電池用染料的研究出現。
在本研究論文中，我們利用推拉電子基以及共軛橋基 (D-π-A) 設計出三種不同的太陽能電池用染料對比上染料性質探討中常被用來比較的染料TTC，而主要針對的方向則是對於共軛橋基以及推電子基之間不同的構成形狀所造成的光物理性質差異探討；實驗中利用核磁共振光譜圖譜 (NMR) 以及質譜儀 (MASS) 鑑定染料分子結構，再經由紫外 - 可見光光譜儀測試出來的光譜以及循環電位儀 (CV) 來加以探討染料分子的光電性質。實驗結果可以發現共軛橋基使用Naphthalene (1,4-Naphthalene / 2,6-Naphthalene) 時，較為平面的2,6-Naphthalene比起1,4-Naphthalene來說，2,6-Naphthalene的吸收波長較為紅移；使用Anthracene (1,4- Anthracene) 在低極性溶劑下中可以維持最大吸收光譜波長在420 nm左右，但是到了溶劑環境極性較高的環境下，由於共平面被嚴重影響，吸收效果不佳。

For the issue of energy crisis, the well-known characteristic of solar cell that can use the endless energy from sunlight being noticed these years, but the photo-to-electron conversion efficiency still can’t reach the expectation. To spread application range of the solar energy, we use Triphenylamine as electron donor groups and also have two different substances (Naphthalene and Anthracene) as π-bridge to synthesize the dyes for solar cell, and this structural modification hopefully increase the range of maximum band to visible light region.
In our research, we use nuclear magnetic resonance spectroscopy (NMR) and mass spectroscopy (MASS) to identify the structures and measure UV-Visible spectroscopy and Cyclic Voltammetry diagram to discuss the photo-physical and electrochemical properties. It turns out that using Naphthalene (2,6-Naphthalene) as π bridge may have much more stable absorption area of wavelength in UV-Visible spectroscopy and some photo-physical property even could beat the reference dye: TTC, which is often used in DSSC research.
