中文摘要 成功合成出JJ1，JJ2和JJ6三種新型染料均以鋅紫質為基本核心結構，其meso-10 位與N，N-烷基-4-（prop-1-yn-1-yl）苯胺電子供體鍵結; meso-20 位與4-（prop-1-yn-1-yl）苯甲酸電子受體鍵結，而鋅紫質的meso-5和meso-15位分別與2,6-雙（十二烷基氧基）苯基或2,6-雙（辛氧基氧基）苯基鍵結，並應用於染料敏化太陽能電池。紫質JJ6在供體上具有最短的烷基（─C4H9），而JJ2包含最長的烷基（─C12H25），而JJ1具有中等長度的辛基。使用這些新型的紫質敏化劑，我們觀察到JJ6在模擬的一個太陽光照度下（AM 1.5 G，100 mW / cm2），短路電流JSC = 18.64 mA / cm2，開路電壓VOC = 0.66 V和填充係數FF = 0.61的情況下具有7.55％的功率轉換效率。)，高於其他兩個； JJ1（7.35％），短路電流JSC = 18.83 mA / cm2，開路電壓VOC = 0.68 V，填充係數FF = 0.60；和JJ2（6.33％），短路電流JSC = 15.69 mA / cm2，開路電壓VOC = 0.62 V，填充係數FF = 0.65。 JJ6和JJ1的功率轉換效率高於JJ2，表明苯胺上的長烷基會降低染料敏化太陽能電池的效率。
英文摘要 Three novel dyes of JJ1, JJ2, and JJ6 featured zinc porphyrin as a basic core structure; N, N-alkyl-4-(prop-1-yn-1-yl)aniline as an electron donor linked to meso-10-position; 4-(prop-1-yn-1-yl)benzoic acid as an electron acceptor linked to meso-20-position; and 2,6-bis(dodecyloxy)phenyl or 2,6-bis(octyloxy)phenyl respectively linked to meso-5 and meso-15-positions of zinc porphyrin have been synthesized and used for dye-sensitized solar cells. Porphyrin JJ6 featured the shortest alkyl group (─C4H9) on the donor, whereas JJ2 contained the longest alkyl groups (─C12H25), and JJ1 has a medium length of octyl groups. With these new porphyrin sensitizers, we observed that JJ6 has 7.55% power conversion efficiency under simulated one-sun illumination (AM 1.5 G, 100 mW/cm2) with JSC = 18.64 mA/cm2, VOC = 0.66 V, and fill factor (FF) = 0.61, which was higher than the other two; JJ1 (7.35%) with JSC = 18.83 mA/cm2, VOC = 0.68 V, and FF = 0.60; and JJ2 (6.33%) with JSC = 15.69 mA/cm2, VOC = 0.62 V, and FF = 0.65. The power conversion efficiency of JJ6 and JJ1 were higher than JJ2, demonstrating that the lengthy alkyl groups on the aniline cause a decrease in efficiency of the devices.
