dc.description.abstract | 為了提高有機太陽能電池的效率,我們計畫採用具自我組裝成規則形態(morphology)之嵌段式共聚物(block-copolymer)作為活性層(active layer)以促進電荷傳導速率。此研究中,我們利用陰離子聚合做成出兩組重量比分別為1:2和 1: 49的poly(3-hexylthiophene)-b-poly(2-vinylpyridine)(P3HT-b-P2VP)之共聚物。此兩組共聚物的特性分別用紫外-可見光光譜(UV-vis)、螢光光譜(PL)、熱裂解分析(TGA)和穿透式電子顯微鏡(TEM)來鑑定。在紫外-可見光光譜和螢光光譜中,跟純P3HT或混摻P3HT-P2VP相比時,共聚物則有藍移現象。當加入非溶劑(甲醇)時,純P3HT與摻合P3HT-P2VP會有聚集效應而導致吸收會紅移;然而,嵌段共聚物的吸收光譜分別在四氫呋喃(THF)或甲醇下幾乎沒改變。當少量的P3HT(2wt%)和P2VP相接時,可看出熱裂解溫度有很大的改變(由352℃提高至381℃)。具有2 wt% P3HT之組成的共聚物呈現球狀形態。總而論之,我們已合成出P3HT-b-P2VP共聚物,將用於製作太陽能電池。 | zh_TW |
dc.description.abstract | To achieve high efficient organic photovoltaics, we propose to use self-assemble highly ordered block-copolymer as active layer to facilitate high charge carrier transport rate. In this study, we used anionic polymerization to synthesize block-copolymer poly(3-hexylthiophene)-b-poly(2-vinylpyridine)(P3HT-b-P2VP) with two compositions, 1: 2and 1: 49 (weight ratio). Their properties were studied by UV-vis, PL, TGA and TEM and compared them with pure P3HT and blend of P3HT-P2VP. In UV-vis and PL spectra, copolymers showed a blue-shift as compared with pure P3HT or blend. A red-shift was observed due to the aggregation of P3HT when a poor solvent, methanol, was added into pure P3HT or blend dissolved in THF. However, the optical spectra of block-copolymer did not change when they were dissolved either in tetrahydrofuran (THF) or methanol. The chemical bond between P3HT and P2VP in the copolymer has retarded the aggregation of P3HT in poor solvent. The decomposition temperatu of copolymer was greatly improved as compared with the neat P2VP, even with only a small amount of 2wt% P3HT, from 352℃ to 381℃. This copolymer containg 2wt% P3HT exhibitsa spherical morphology. In conclusion, we have synthesized P3HT-b-P2VP copolymer which will be used in photovoltaics. | en |
