2,2'和3,3'取代以噻吩並異靛藍為主體的小分子在有機光伏打電池上之應用

2,2' and 3,3' Substituted Thienoisoindigo-Based Small Molecules for the Applications of Organic Photovoltaics

指導教授 : 陳志欣

摘要


在這裡,以噻吩並異靛藍 ( TII ) 作為主結構合成出7個染料分子 ( H1~H7 ),並且應用在有機光伏打電池中。   這些染料分子使用咔唑( H1 )、N-苯基咔唑 ( H2,H4,H7 )、1,3-二 ( 9H-咔唑-9-基)苯 ( H3 )、三苯胺 ( H5,H7 )、苯環 ( H6 ) 作為電子供體 (D),而噻吩並異靛藍 ( TII ) 當作電子受體 (A)。這樣D-A-D結構使分子可以呈現較強的分子內電荷轉移,因此可以吸收來自可見光區和部分近紅外光區的能量。   使用H2/PC61BM作為主動層製備的體異質接面 ( BHJ ) 的電池元件,呈現出0.82%的光電轉換效率,表示以噻吩並異靛藍 ( TII ) 作為主結構染料分子應用在近紅外區有機光伏打電池的潛力。

In this research, we synthesized a series of thienoisoindigo (TII)-based small molecules (H1-H7) and applied them to develop organic photovoltaics (OPVs). The TII-based small molecules use carbazole (H1), N-phenylcarbazole (H2, H4, H7), and 1,3-di(9H-carbazol-9-yl) benzene (H3), triphenylamine (H5, H7), benzene (H6) as electron donor (D), while TII as electron acceptor (A). Such D-A-D structure allowed the molecule to exhibit a strong intramolecular charge transfer such that they can absorb the light from visible and partially near-infrared (NIR) region. The bulk heterojunction (BHJ) solar cell device fabricated by using H2/PC61BM as the active layer exhibited a power conversion efficiency (PCE) of 0.82%, showing the potential of TII-based dyes for NIR organic photovoltaics (OPVs).
