The reasonable selection and optimization of donor-acceptor units allow the band gap tuning as well as the light absorption ability and the energy levels of the photoactive layer of Bulk Heterojunction (BHJ) solar cells. In this work, a series of new quin

Fluorinated and chlorinated donor-acceptor alternating copolymers, F-PBTQT and Cl-PBTQT, were synthesized and used as donor materials for polymer solar cells. Among them, Cl-PBTQT exhibited much better device performance, and a single-junction efficiency of 8.16% was achieved, indicating that chlorination could be a better strategy than fluorination to develop highly efficient polymer donors.

The invention belongs to the organic chemical field, and discloses a chloroquinoxaline compound, a structural general formula of the conjugated polymer is shown as I. The compound introduces a fluorine atom with a strong electrosorption characteristic on quinoxaline, thereby the HOMO energy level of the material can be effectively reduced, and the open-circuit voltage of a polymer photovoltaic cell can be enhanced. By using cyclic voltammetry determination of the HOMO energy of the compound, compared with a non-chloroquinoxaline derivative, the HOMO energy level of a single fluoropolymer is lower by 0.02-0.15eV than that of the non-chloroquinoxaline, and the HOMO energy level of the double fluoro polymer is lower by 0.05-0.3eV than that of the non-chloroquinoxaline. The compound can be taken as an intermediate of a polymer photovoltaic material for preparing the polymer photoactivity material with excellent performance. By using cyclic voltammetry determination of the HOMO energy of the compound A-I, compared with the non-chloroquinoxaline derivative, the HOMO energy level of the single fluoropolymer is lower by 0.02-0.15eV than that of the non-chloroquinoxaline, and the HOMO energy level of the double fluoro polymer is lower by 0.05-0.3eV than that of the non-chloroquinoxaline.
