Abstract

fetched live from OpenAlex

The interaction between the excited sensitizer and the redox couple in a photochemical solar cell is an important factor that can decrease the photon-conversion efficiency. We have now employed C 60 clusters to separate the Ru(bpy) 2 (dcbpy) 2+ (Ru(II) complex) and I 3 - /I - couple to minimize the sensitizer−redox couple interactions. The C 60 -modified electrodes (viz., OTE/SnO 2 /Ru(II)/C 60 and OTE/TiO 2 /Ru(II)/C 60 ) delivered photocurrent with greater efficiency than did the SnO 2 and TiO 2 films modified with only a Ru(II) dye (viz., OTE/SnO 2 /Ru(II) and OTE/TiO 2 /Ru(II)). The luminescence quenching of Ru(II)* by I 3 -, which occurs with a rate constant of 1.9 × 10 10 M -1 s -1, is suppressed following the deposition of a layer of C 60 clusters. This paper presents a novel concept of employing a redox-active molecular assembly as an electron relay that greatly minimizes the interaction with the excited dye while maintaining the effectiveness of the regeneration cycle.

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.
