Synthesis and Characterization of alkyloxy side chain containing-2,1,3-Benzoselenadiazole-Based low band gap Conjugated Polymer for Organic Photovoltaic Cells |
| 초록 |
New donor-acceptor (D-A) type conjugated polymers containing 2,1,3-benzoselenadiazole unit were synthesized by Stille coupling polymerization reactions as donor materials for use in organic photovoltaic cells (OPVs). The synthesized polymers were soluble in common organic solvents, and the resulting polymer solutions could be used to form smooth and uniform thin films by spin-casting. The synthesized polymers were found to exhibit good thermal stability, losing less than 5 % of their weight upon heating to approximately 300 °C. The intra-molecular charge transfer interaction between the electron donating and electron accepting blocks in the polymeric backbone induced a broad absorption from 300 to 750 nm. The optical band gap energies of the polymers were measured to be 1.74 - 1.67 eV depending on the polymer structure. |
