Synthesis and characterization of Poly (3-hexylthiophene)-b-Poly (2-vinylpyridine)

, 2007
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 ...
