Synthesis and Characterization Polythiophene Derivative Containing Cyanoacetic Groups for Use in Organic Solar Cells |
| 초록 |
A novel push-pull copolymer was synthesized by Stille coupling reaction. The synthesized polymer was characterized by 1H NMR and FT-IR Spectroscopic studies. The synthesized materials have moderate solubility in organic solvents such as chloroform, chlorobenzene, and dichlorobenzene. The material has a good balance of donating group and withdrawing group.We calculated the optical band gap of 1.74 eV from the edge wavelength of UV-vis absortion spectrum. From the GPC, it shows an average molecular weight of 7.5 x 103 g/mol with a polydispersity index of 1.19. We present electrochemical, optical, thermal properties of the synthesized polymer. Solar cell performances of the polymer blended with PC70BM will be presented in detail. This compound can be a promising material for printing process and tendem solar cells. |
