| dc.description.abstract | 本論文設計並合成三個小分子有機光伏打電池的供體材料 ( DCA-T-TTAR、DCA-TH-TTAR 和 DCA-bT-TTAR )，這些化合物為對稱性的受體-供體-受體結構，以十五烷基鏈取代的 TTAR 為中心供體，再接上不同個數的噻吩，最後末端受體為氰基乙酸辛酯。利用可見光紫外光吸收光譜儀、循環伏安法、熱重分析儀分析進行物性測試，藉由光學和電化學測定推算出能階，對這一系列化何物進行徹底的研究調查，得到明確地結構與性能之間的關係。其中，DCA-bT-TTAR 以簡單的溶液旋轉塗佈製程方式初步測得效率為 2.36 %，因此，以 TTAR 為核心確實能夠開發成新的有機光伏材料。 | zh_TW |
| dc.description.abstract | Three new tailor-made molecules ( DCA-T-TTAR, DCA-TH-TTAR, and DCA-bT-TTAR ) were strategically designed and convergently synthesized as donor materials for small-molecule organic solar cells.
These compounds possess a acceptor−donor−acceptor molecular architecture, TTAR as the central building block with pentadecyl substituted alkyl chain and octyl cyanoacetate terminal units with different linkage of thiophene.
Physical properties such as absorption spectroscopy, cyclic voltammetry and thermal gravimetric analysis were examined. Also Photophysical and electrochemical properties as well as energy levels of this series of donor molecules were thoroughly investigated, affording clear structure−property relationships.
Among them, DCA-bT-TTAR shows power conversion efficiency 2.36 % has been achieved using the simple solution spin-coating fabrication process. The results demonstrate that structure fine turning could cause significant performance difference.Thus, TTAR-related compounds are promising for developing new organic solar cells materials. | en_US |
