dc.description.abstract | The excitation intensity dependent carrier dynamics of blends with PC[70] BM of three new medium-band gap conjugated polymers with central chalcogen heteroatoms, PBDTfDTBX (X = O, T(Sulphur), Se) were studied. The PBDTfDTBX polymers (Poly[4,8-bis(5-(2-butyloctyl)thiophene-2-yl)benzo[1,2-b; 4,5-b']dithiophene-alt-4,7-bis(4-(2-ethylhexyl)-2-thienyl)-dithieno[3',2': 3,4;2".,3".: 5,6]benzo[1,2-c] [1,2,5] furazan or thiadiazole or selenadiazole]) have symmetrical structures but exhibit different solar cell performances. In this study, we determined how the photogenerated charge carrrier dynamics of the PBDTfDTBX: PC[70] BM blends varies with the heteroatom by performing transient absorption measurements at various excitation intensities. It was found that the charge carrier dynamics of the PBDTfDTBX blends with X = T or Se heteroatoms are dependent on the excitation intensity whereas that of the PBDTfDTBO blend is independent of the intensity. The photogenerated charge carrier dynamics of the PBDTfDTBO: PCBM, PBDTfDTBT: PCBM, and PBDTfDTBSe: PCBM blends were all modeled globally and rates were estimated for different photophysical processes occurring on different time scales. | - |
