| Abstract |
The novel copolymers using fluorene and fluorinated quinoxaline were synthesized by Suzuki and Stille coupling reactions. The polymers had good solubility in organic solvent such as benzene derivative (toluene, chlorobenzene and o-dichlorobenzene). The absorption spectra in solution had maximum peak at 442 to 498 nm and in solid film had maximum peaks at 448 to 543 nm. These polymer have improved π–π interchain interactions in the film state compared to those in solution.
These polymer observed a narrow bandgap 1.93 to 2.14eV. A highest occupied molecular orbital (HOMO) energy level showed at -5.59 to -5.67 eV and lowest unoccupied molecular orbital (LUMO) energy of -3.51 to –3.72 eV. PSCs made from copolymer:PC70BM (1:1.5 wt%) + 3vol% DIO blends showed maximum power conversion effiencies (PCE) values of (3.98, 2.91 , 3.33, 3.55 and 3.07%), respectively. |
