Polymer organic solar cells

polyVERSE polymer data for polymer solar-cell properties. Records retain polymer representations, source property names, and available composition or measurement conditions.

Part of the Molecular Datasets collection.

data/ contains rows with readable molecular structures; identical observations are collapsed. observations/ contains all source rows.

Source label columns are text, including values such as <10. SMILES_original retains the input representation; SMILES_canonical provides a canonical representation. structure_key groups molecular components, and structure_status records parsing outcomes.

Data quality

  • experiment: Source label origin.
  • multi-source: Measurements compiled from multiple sources.
  • valid structures: Molecular structure parsing results.
  • replicate variability: Variation among repeated measurements relative to overall label variation.
  • 100% label coverage: Median fraction of molecules labeled per task.
  • 120 molecules per task: Median molecules with a label per task.

Dataset notes

  • Repeated structures at different conditions or compositions are not duplicate measurements.
  • Repository code license does not supersede the GTRC data terms.
  • Literature records were extracted with LLM assistance and include original DOI and device-processing context.
