    摘要註: 近年來由於石化能源的大量使用,可想而知在未來的數十年後,石化能源將有消耗殆盡的一天,由於「能源危機」所帶來的嚴重影響,勢必在新能源的找尋與開發是刻不容緩的,而眾多的「可再生能源」當中,太陽能是最受到期待與注目的,也將是未來的趨勢。其中光敏化太陽能電池由於其製作成本低廉、可撓性以及加工性質大而具有工業化潛力與大面積生產等多項優點,是被寄予厚望的產品。而在本研究探討設計兩個具苯胺官能基之有機染料,首先利用實驗室開發方法合成呋喃主體衍生物,並利用Suzuki-Miyaura coupling耦合反應合成具苯胺官能基,並將有推電子基效果及具拉電子基效果之分子摻雜入主體當中,藉此增加電荷在主體上的傳遞,並增加其光譜吸收的範圍,而在另一側鏈上加入塞吩分子除了可以調節材料能階、增加材料的特性,還可以藉由本身材料性質增加對太陽光子的吸收,再將其光電子轉移至TiO2上。本計畫擬設計兩個具苯胺結構之染料分子,並藉由苯胺類結構有良好的光收成能力,在設計二維之染料結構個別控制其HOMO以及LUMO能階,因此可以調控適合的能階與二氧化鈦以及電解質做搭配,並改善其分子在堆疊的情況,可明顯的改善電子在分子與分子間的傳遞。 Recent years due to extensive use of fossil fuels, we can imagine in the next few decades, fossil fuels will be exhausted one day. Due to the severe impact brought by “energy crisis”, it is inevitable to discover and develop renewable energy. Among all of the renewable energy, solar energy is the center of attention and it will be the future trend. Wherein Dye-Sensitize solar cells due to its low production cost, flexibility, large industrial potential and large-scale production, thus, it gets extremely attention and high hopes.In the design of this study was to investigate the two functional groups with organic dye amine. Using the method of synthesis of furan derivatives subject and using Suzuki-Miyaura coupling reaction of synthesis coupled with amine functional groups, and will have the effect of electron donating and with an electron-withdrawing effect of the molecule doped into the body which, to increase the charge transfer on the body and increase its spectral absorption range, while on the other side chain embedded with thiophene molecule material can be used to adjust the material bands, enhance its properties, and increase their solar photons absorption ability and then transform the electron on TiO¬2. The study intends to generate several amine group dye structure utilizes low band gap and photon characteristics in two dimension D-π-A system.This study intends to design two structures with amine dye molecules which poses superior light absorption ability, so in the design of two-dimensional structure of dye can control HOMO and LUMO energy level individually. Therefore, the appropriate energy levels can be regulated and an electrolyte to coordinate with TiO¬2 and improve their conditions of the stack structure which can be significantly improved electron transfer between molecules and molecules.
