| Summary: | 博士 === 國立臺北科技大學 === 工程科技研究所 === 103 === The research project of this thesis is mainly studied the synthesis of Photoelectronic Polymer and its application on polymer solar cells. In the synthesis section, we divided into two topics to discuss. For the first topic, we have synthesized polymer, poly [2-methoxy 5-(2-ethylhexoxy)-1,4-phenylenevinylene] MEH-PPV, with varied molecular weights via controlled polymerization conditions. For the second topic, we changed the alkyl group of thiophene 3 position to synthetize 4 different poly(3-alkylthiophene)(P3AT) with poly(3-hexyl thiophene) (P3HT), poly(3-octyl thiophene) (P3OT), poly(3-decanal thiophene) (P3DT),and Poly (3- dodecylthiophene-2,5-diyl) (P3DDT). We used gel permeation chromatography(GPC) to study the Photoelectronic Polymer properties。 All effects of molecular weight (Mw) and polydispersity (PDI) on emission properties and the morphology of polymer film are discussed by the measurements of Gel Permeation Chromatography (GPC), atomic force microscopy (AFM) and scanning electron microscopy (SEM)。
