Low band gap polymers have been engineered to have appropriately aligned EHOMO/ELUMO electronic levels relative to PCBM, optimized side chains to enhance solubility while enabling good interchain interactions, and low band gaps(Eg) to increase the harvested range of the solar spectrum. Fluorinated molecules have been made both EHOMO and ELUMO are lowered, leading to enhanced open-circuit voltage (Voc) and have enhanced such as great thermal and solubility upon incorporation of fluorine on the acceptor unit in a D-π-A conjugated polymer backbone. For enhancing the good solubility and thermal stability of perfluorinated aromatic units, we designed and synthesized a series of various perfluorinated aromatic units containg thieno[3,4-c]pyrrole-4,6-dione (TPD)-based polymers. Here, synthesis and characterization of D-π-A copolymer perfluorinated TPD acceptor for polymers with solar cells will be described. |
