Soluble porphyrin donors for small molecule bulk heterojunction solar cells
Abstract
This paper describes the rational design of porphyrin donors for application in solution-processed small molecule bulk heterojunction (BHJ) solar cells. The porphyrin donors were designed to possess high solubility and strong intermolecular interactions, via the appropriate selection of peripheral substituents: these molecules bear tetraethynyl porphyrin cores with two aromatic and two aliphatic groups in a trans manner. We have also demonstrated the substitution effect on the aromatic groups: energy levels, solubility and film morphology were significantly modified by the substituents, which consequently influenced the efficiencies of the solar cells as well. After optimization, the device based on [5,15-bis(phenylethynyl)-10,20-bis[(triisopropylsilyl)ethynyl]porphyrinato] magnesium(II) (2):PC60BM showed a PCE of 2.5%.

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.
