有機共軛酸在太陽能電池染料的應用

Abstract

中文摘要 在本篇論文中，我們研發以有機共軛酸當作主要骨架的有機化合物染料4-(4-二甲胺苯)1,3-環己二烯羧酸 (5)、4-(4-二苯胺苯)1,3-環己二烯羧酸 (10)和4-(4-(9H-咔唑基)苯)1,3-環己二烯羧酸 (15)來當作染料敏化太陽能電池的材料，並測試、探討其物理性質，以作為將來發展類似結構時的依據。在這些合成的有機化合物染料結構中，均包含了環己二烯(1,3-cyclohexdiene)的架構，這可使整個結構的穩定度大幅提高。 在物理性質方面，我們測試化合物(5、10、15)其個別的吸收光譜、螢光激發光譜和電化學性質。同時也將其製作成元件(染料敏化太陽能電池)，利用太陽光模擬及特定波長光束輸出系統進行光電轉換效率(η)與單色光轉換效率(IPCE)的測試。

Abstract In this thesis, we synthesized three organic dye-sensitized compounds 4-(4-(Dimethylamin)phenyl)cyclohexa-1, 3-dienecarboxylic acid (5)、4-(4-(Diphenylamino)phenyl)cyclohexa-1, 3-dienecarboxylic acid (10) and 4-(4-(9H-Carbazol-9-yl)phenyl)cyclohexa-1, 3-dienecarboxylic acid (15). Their physical properties were investigated. All of our compounds possess 1,3-cyclohexdiene conjugated units as the skeleton and enhance their structure stability. According to the information we obtained, more related compounds and their application could be further developed. All of these compounds were characterized by UV/VIS spectrophotometer, fluorescence spectrophotometer and cyclic voltammetry. The photoconversion and incident photo-to-current efficiencies of these compounds were inspected using the AM 1.5 simulated solar light and irradiation of monochromic light system.
