Low bandgap polymers were used as photo-active material in polymer solar cell andrequired good solubility in common solvent and high molecular weights. However, a lot of polymers with donor-acceptor structures have low molecular weight and poor solubility. Because acceptor units have more than 3 ring structures, it was not efficiently positioned for polymerization due to twisting or steric hinderance. For overcoming those problems, we investigated alternative and random polymer, consist of the monomers used for push-pull structure. |
