Abstract

fetched live from OpenAlex

Over the past decades, indolo- and diindolocarbazoles have been incorporated in bulk heterojunction solar cells (BHJSCs) as electron donors - either as small molecules or within the backbone of conjugated push-pull polymers. Recently, these units were used as nonfullerene electron acceptors, resulting in superior photoconversion efficiencies (PCEs). Their motif consists of D-A or A-D-A units (D = electron-donor; A = electron-acceptor). This review focuses on the reasons why that is so.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
