| 제목 | Synthesis and Characterization of Copolymer based on BDP unit for Inverted Oraganic Photovoltaics |
| 초록 | Bulk-heterojunction(BHJ) type Organic photovoltaics(OPVs) have attracted tremendous attention due to their unique advantages including low cost, light weight, and potential uses in flexible and large-area devices. However degradation in air for conventional BHJ-OPVs is serious problem. To improve this point, Inverted OPVs(IOPVs) are introduced to improve low stability about air. In IOPVs have a structure in which the metal acts as the anode and the transparent electrode acts as the cathode. The Benzo[2,1-b:3,4;b']dithiophene (BDP) unit decreases electron richness of the flanked bithiophene unit, which provides a low-lying highest occupied molecular orbital (HOMO) energy level. To extend π-conjugation length, we also introduced oxadiazole acceptor unit and bithiophene spacer. In this study, we synthesized polymers using Stille coupling reaction. The synthesized polymer is characterized by 1H-NMR, GPC, TGA, UV, CV and fabricated device was measured. |
