A Selenium‐Substituted Low‐Bandgap Polymer with Versatile Photovoltaic Applications
Abstract
A reduction of the bandgap and an enhancement of the charge transport properties of a LBG polymer (PBDTT-DPP) can be achieved simultaneously by changing the sulfur atoms on the DPP unit to selenium atoms. The newly designed polymer, PBDTT-SeDPP (Eg = 1.38 eV), shows excellent photovoltaic performance in single junction devices with power conversion efficiencies (PCEs) over 7% and photo-response up to 900 nm. A tandem polymer solar cell and a visibly transparent solar cell based on PBDTT-SeDPP show 9.5% and 4.5% PCEs, which are superior to those based on PBDTT-DPP.

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.
