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.
