Properties of alternating copolymers based on naphtho[2,1-b:3,4-b′]dithiophene (NDT) for solution-processed polymer solar cells. |
| 초록 |
In this work, a newly designed naphtho[2,1-b:3,4-b′]dithiophene derivative which plays a role of electron donor unit has been prepared. Among electron-rich unit, NDT is an ideal conjugated unit for new photovoltaic material because of large planar structure for better π-π stacking. We compared properties of the polymers based on NDT with strong electron donating moiety and strong electron withdrawing moiety in organic solar cells view. Also, we analyzed the film morphology of the bulk heterojunction mixtures with [6,6]-phenyl C71-butyric acid methyl ester (PCBM) by atomic force microscopy and transmission electron microscopy. We report the characterization and device performance of the polymers consisted of thiophene (T) moiety or benzothiadiazole (BT) moiety. |
