Nature‐inspired light‐harvesting liquid crystalline porphyrins for organic photovoltaics

Abstract

A new class of nanoscale light‐harvesting discotic liquid crystalline porphyrins, with the same basic structure of the best photoreceptor in nature (chlorophyll), was synthesized. These materials can be exceptionally aligned into a highly ordered architecture in which the columns formed by intermolecular π–π stacking are spontaneously perpendicular to the substrate. The homeotropic alignment, well confirmed by synchrotron X‐ray diffraction, could not only provide the most efficient pathway for hole conduction along the columnar axis crossing the device thickness, but also offer the largest area to the incident light for optimized light harvesting. Their preliminary photocurrent generation and photovoltaic performances were also demonstrated. The results provide new and efficient pathways to the development of organic photovoltaics by using homeotropically aligned liquid crystal thin films.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • After annealing, the C1-based device achieved a Jsc of 3.990 mA cm−2 and a PCE of 0.712%.

    “the C1 based device achieved a J sc of 3.990 mA cm 2 and a PCE of 0.712%”
  • Thermal annealing of C1/C2 liquid crystalline porphyrin donors resulted in porphyrin alignment in the active layer blend and yielded high Jsc and PCE.

    “A high J sc and PCE were obtained by thermal annealing, which resulted in the porphyrin alignment in the active layer blend.”
  • After annealing, the C2-based device exhibited a Jsc of 5.02 mA cm−2 and a PCE of 0.775%.

    “the C2 based device exhibited a J sc of 5.02 mA cm 2 and a PCE of 0.775%”

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.
