Abstract

Dye-sensitized solar cells have gained widespread attention in recent years because of their low production costs, ease of fabrication and tunable optical properties, such as colour and transparency. Here, we report a molecularly engineered porphyrin dye, coded SM315, which features the prototypical structure of a donor-π-bridge-acceptor and both maximizes electrolyte compatibility and improves light-harvesting properties. Linear-response, time-dependent density functional theory was used to investigate the perturbations in the electronic structure that lead to improved light harvesting. Using SM315 with the cobalt(II/III) redox shuttle resulted in dye-sensitized solar cells that exhibit a high open-circuit voltage VOC of 0.91 V, short-circuit current density JSC of 18.1 mA cm(-2), fill factor of 0.78 and a power conversion efficiency of 13%.

  • The first porphyrin DSSC, employing Cu-2α-oxymesoisochlorin, achieved a power conversion efficiency (PCE) of 2.6% in 1993.

    “The first porphyrin DSSC, employing Cu-2α-oxymesoisochlorin, achieved a power conversion efficiency (PCE) of 2.6% in 1993 [64].”

    From Three-Dimensional Solar Harvesting with Transparent Spectral Selective Photovoltaics in Agrivoltaics (2025) · cites this paper as [64]

    The introduction (section D; page unavailable) discusses later porphyrin sensitizers and their efficiencies, but does not identify a first porphyrin DSSC. Searches for Cu-2α-oxymesoisochlorin, 1993, and 2.6% found no passage in our copy addressing the claimed device or result. (LLM, conf=0.72)

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.
