Narrow band gap benzodithiophene and quinoxaline bearing conjugated polymers for organic photovoltaic applications

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

Synthesis and photovoltaic properties of copolymers with a fluoro quinoxaline unit

Two novel accepter units, namely, difluoroquinoxaline and monofluoroquinoxaline, were prepared and used for the synthesis of the conjugated polymers containing electron donor–acceptor pairs for use in organic photovoltaics. The introduction of a fluorine atom into the quinoxaline moiety resulted in polymers with lowered highest occupied molecular orbital (HOMO) energy levels; this increased the open circuit voltage of the devices based on the synthesized polymers. The conjugated polymers containing difluoroquinoxaline and monofluoroquinoxaline, namely, thiophene and benzodithiophene, were synthesized using the Stille polymerization reaction to produce PEHBQxF2, PEHBQxF1, PEHBDTQxF2, and PEHBDTQxF1. The HOMO energy levels of PEHBQxF2, PEHBQxF1, PEHBDTQxF2, and PEHBDTQxF1 were determined to be ?5.66, ?5.52, ?5.54, and ?5.39 eV, respectively. The device with PEHBDTQxF2/PC71BM (1:2, w/w) and containing diiodooctane (3 vol %) exhibited the best photovoltaic performance, with its VOC being 0.79 V, JSC being 10.44 mA/cm2, FF being 68%, and PCE being 5.58%.

[...] compound

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.
