Improved Photovoltaic Properties of Donor–Acceptor Copolymers by Introducing Quinoxalino[2,3-b′]porphyrin as a Light-Harvesting Unit
Abstract
Donor–acceptor (D–A) copolymerization is an effective approach to construct low bandgap polymers with tunable electronic energy levels for the application as donor materials in polymer solar cells (PSCs). Usually, D–A copolymers possess an intramolecular charge transfer absorption band at long wavelength direction, so that the absorption of the polymers is broadened. However, absorption at short wavelength direction is also important and should be broadened and enhanced to increase the short-circuit current density ( J sc ) of the PSCs. In this study, a series of low bandgap conjugated polymers, P(QP4-BT-DPP1), P(QP1-BT-DPP1), and P(QP1-BT-DPP4), based on two acceptor units quinoxalino[2,3- b ′]porphyrin (QP) and diketopyrrolopyrrole (DPP) connected by oligothiophene donor units, were designed and synthesized by palladium-catalyzed Stille-coupling polymerization. As a complementary light-harvesting unit, QP was first introduced into the D–A conjugated polymers for improving the photovoltaic performance of PSCs. The incorporation of QP broadened and enhanced the absorptions of short wavelength photons as well as kept the well-tuned electronic energy levels and bandgap of the pristine D–A copolymer. Moreover, para-linked QP improved coplanarity and extended π-conjugation along the polymer backbone. As a result, P(QP1-BT-DPP4) with a proper feed ratio (10 mol %) of QP showed an increased J sc of 11.85 mA/cm 2 without sacrificing open-circuit voltage ( V oc ) or fill factor (FF)…

The different performances of these polymers are also related to crystallinity, and an increase of the QP ratio leads to a less ordered structure because of the hindrance of the bulky QP unit.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
