Abstract

fetched live from OpenAlex

The aqueous photocathode activity of regioregular poly(3-hexylthiophene), a p-type organic semiconductor, is presented. Photocurrents up to 20 μA cm−2 under 100 mW cm−2 AM 1.5D irradiation were observed. The highest photon-to-current conversion efficiency was produced for the thinnest films studied (40 nm), attaining a value of 0.55%, which is 10 times greater than reported for regiorandom P3HT. Increasing the thickness of the polymer increased the photocurrent but decreased the photoconversion efficiency. UV-vis absorption and fluorescence spectroscopy indicates protonation is restricted to the surface of the films in aqueous acid. A mechanism for the photocathode activity involving reduction of surface-protonated P3HT is proposed.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
