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%.

Performance comparison of fluorinated and chlorinated donor-acceptor copolymers for polymer solar cells

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.

[...] 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.

Fluorination as an effective tool to increase the open-circuit voltage and charge carrier mobility of organic solar cells based on poly(cyclopenta[2,1-b:3,4-b′]dithiophene-alt-quinoxaline) copolymers

The effect of fluorination on the optoelectronic properties and the polymer : fullerene solar cell characteristics of PCPDTQx-type (poly{4-(2′-ethylhexyl)-4-octyl-4H-cyclopenta[2,1-b:3,4-b′]dithiophene-alt-2,3-bis[5′-(2′′-ethylhexyl)thiophen-2′-yl]quinoxaline}) low bandgap copolymers is reported. The introduction of fluorine atoms on the quinoxaline constituents is an effective way to lower the HOMO and LUMO energy levels of the alternating copolymers, resulting in an enhanced open-circuit voltage for the devices based on the fluorinated polymers (～0.1 V per F added). Furthermore, fluorination also improves the charge carrier mobility in the bulk heterojunction blends. Despite the formation of unfavorable photoactive layer morphologies, the best solar cell performance is obtained for the copolymer prepared from the difluorinated quinoxaline monomer, affording a power conversion efficiency of 5.26% under AM 1.5G irradiation, with an open-circuit voltage of 0.83 V, a short-circuit current density of 11.58 mA cm-2 and a fill factor of 55%.

Synthesis and photovoltaic properties of an alternating polymer based fluorene and fluorine substituted quinoxaline derivatives

An alternating polymer (PFOFTQx) with 9,9-dioctylfluorene (FO) as electron-rich unit and fluorine substituted quinoxaline (FTQx) as electron-withdrawing unit was synthesized and characterized. PFOFTQx showed similar absorption property with that of the counterpart polymer without fluorine atom (synthesized APFO-15). However, the low-lying highest occupied molecular orbit (HOMO) energy level of PFOFTQx was -5.37 eV, about 0.07 eV smaller than that of synthesized APFO-15. In order to study the photovoltaic properties of the materials, polymer solar cells (PSCs) were fabricated with PFOFTQx as donor blended with [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) as acceptor. The power conversion efficiency (PCE) of PSC was 1.77% with a high open-circuit voltage (Voc) of 0.90 V for an optimized PFOFTQx:PC61BM weight ratio of 1:5, in comparison with that of synthesized APFO-15-based device (PCE of 1.60% with Voc of 0.77 V). This study indicated that fluorine substituted quinoxaline-based polymers would be promising material with a higher Voc for the application in polymer solar cells.
