Characterization and photovoltaic performances of two new fullerene derivatives used as electron acceptor in BHJ organic solar cells |
| 초록 |
[60] fullerene derivatives are the focus of considerable research due to their important roles as electron acceptors in OPV cells and other fields. In this study, we synthesized the following two novel fulleropyrrolidine derivatives: C60-fused N-methyl-(4-hexyloxybenzen-2-yl) pyrrolidine, (p-HOPF) and C60-fused N-methyl-(2-hexyloxybenzen-2-yl) pyrrolidine, (o-HOPF). Structural assignments of the two fullerene derivatives were made through 1H NMR, 13C NMR and FAB-MS. We also measured the optical properties of p-HOPF and o-HOPF through UV/Vis spectrophotometer and further measured their electrochemical properties by using cyclic voltammetry. In order to study the position effects of the substituent groups on photovoltaic performance, photovoltaic devices were fabricated. The highest power conversion efficiency, 0.71%, was achieved when using o-HOPF as the electron acceptor and 0.54% was achieved when using p-HOPF as electron acceptor. |
