Synthesis and Photovoltaic properties of copolymers based on 2,7-Bis-(3,4-bis-hexyloxy-thiophen-2-yl)-fluoren-9-one |
| 초록 |
In order to improve incident to photon conversion efficiency (IPCE) of photovoltaic devices (PVs), the materials should have low band gap energy less than 1.8 eV. High Voc is also critical parameter for improving PV efficiency. To make the -conjugated polymers showing wide absorption range and high Voc, we introduce 2,7-Bis-(3,4-bis-hexyloxy-thiophen-2-yl)-fluoren-9-one. We synthesize new copolymers based on 2,7-Bis-(5-bromo-3,4-bis-hexyloxy-thiophen-2-yl)-fluoren-9-one and derivatives of 9,10-Bis-hexyloxy-phenanthrene by the suzuki coupling reaction to get wide absorption range and high Voc. In this presentation, we will report synthesis, optical, and electrochemical properties of new copolymers. Also, the PV properties based on blend of new copolymer and PCBM will be discussed. |
