OPV-DB is a literature-mined organic photovoltaic device performance database. The current website mirrors the publication-facing 2026 Q3 release, OPV-DB v1.1.0:

• Zenodo v1.1.0 DOI: https://doi.org/10.5281/zenodo.22177960
• Zenodo all-versions DOI: https://doi.org/10.5281/zenodo.20841542
• Archived dataset: https://zenodo.org/records/22177960
• Full archive: 39,998 single-junction OPV device records
• Source DOIs: 8,073 normalized source DOIs
• Strict performance benchmark: 32,457 records
• Strict molecular benchmark: 22,467 records
• All four photovoltaic metrics: 38,606 records
• Donor and acceptor SMILES: 27,361 records

See the v1.1.0 release notes and the detailed Chinese comparison with v1.0.0 for the dataset upgrade, benchmark continuity, and molecular-curation summary.

The web app is served from the docs/ directory through GitHub Pages. It loads docs/opv_data.json, which is generated from the archived v1.1.0 release. The root Active_Database.csv is a byte-identical CSV mirror of data/opv_devices_full.csv in that release. The browser payload adds only display metadata and tier-membership flags; the 37 public device fields retain their release values.

Files

• docs/index.html: static browser interface.
• docs/opv_data.json: browser JSON generated from the public release, with release metadata stored once at the top level and records in records.
• Active_Database.csv: CSV mirror of data/opv_devices_full.csv from the Zenodo release.

Recommended Citation

Please cite the archived dataset rather than a mutable website copy:

@dataset{qiu2026opvdb,
  author    = {Qiu, Jiangjie},
  title     = {OPV-DB: a literature-mined organic photovoltaic device performance database},
  year      = {2026},
  publisher = {Zenodo},
