| Summary: | 碩士 === 雲林科技大學 === 化學工程與材料工程研究所 === 96 === A novel photosensitizer dye and a series of polymer electrolytes were synthesiged in this study. First part, a novel organic dye 5,7-Bis-(tolyl-phenyl)-2,3-bis-(4-(2-ethyl-hexyloxy)-phenyl-thieno[3,4-b]pyrazine (TEP) was designed and synthesized for in application organic solar cells (OSCs). The absorption wavelength of the TEP molecule was ranged from 300 to 600 nm. OSCs using TEP/PCBM blends as a active layer waere fabricated by spin-coating method. The maximum energy conversion efficiency and short-current density were achieved 0.173% and 1.796 mA/cm2. In second part, on carbazole, fluorine, and thiophene based conjugated copolymer containing, side chain quaternariged ammonium iodides were synthesiged. The ionic conductivity were slightly enhanced by incorporation 1wt% polymer electrolyte content in liquid electrolyte as compared to the liquid electrolyte. The quaternary ammonium iodide containing polymer electrolyte was successfully used in dye-sensitized solar cell application, High energy conversion efficiency 3.734% and large short-current density 10.388 mA/cm2 were observed.
