本文設計合成出以2-phenylthiophene作為架橋的傳統D-π-A 形式有機光敏染料DD101，接著進行改良設計合成出以2,2’-(1,3-phenylene)bis-thiophene作為架橋的2D-π-2A形式有機光敏染料DD104、DD113及DD114，進而研究不同電子提供基團對於2,2’-(1,3-phenylene)bis-thiophene架橋結構之效率影響。;Among the many renewable energy, inexhaustible solar energy is the most attended one. Dye-sensitized solar cells possessing the advantages of low-cost, simple process, multi-color, penetration and flexibility, has become one of the key technology to developed.
The photosensitizer is one of important components which affecting the solar cell efficiency in the dye-sensitized solar cells. Compared to the ruthenium metal complexes based sensitizers, the metal-free organic sensitizers shows following advantages：high molar extinction coefficient, easy for structural modification, low cost and lower environmental pollution, etc., and hence, attracted large of studies.
The sensitizers DD101 representing the D-π-A configuration, in which 2-phenylthiophene as the π-bridge of the dye, were designed and synthesized. Next, we made modification to design the series of sensitizers DD104, DD113 and DD114 to represent the 2D-π-2A configuration, in which 2,2’-(1,3-phenylene)bis-thiophene were incorporated in the π-bridge of the dye. Then, further investigation of various of donors which affect the power conversion efficiency of 2,2’-(1,3-phenylene)bis-thiophene sensitizers are studied to.
