Abstract

fetched live from OpenAlex

A ternary organic solar cell (TOSC) P5 :PC 71 BM:Y6 (1:0.2:1) composed of an electron donor 3,4‐ethylenedioxythiophene (EDOT)/diketopyrrolopyrrole (DPP)‐containing [Pt] (II) polyyne oligomer P5 with the acceptors PC 71 BM and Y6 shows a significant enhancement of the average power conversion efficiency (PCE) to 16.0% in comparison to the reported binary organic solar cells (OSCs) ( P5 :PC 71 BM (1:1.4), PCE = 9.4%; P5 :Y6 (1:1.2), PCE = 14.8%). Photophysical investigations carried out on the two binaries and on the ternary highlight the role of PC 71 BM to increase the rise time of electron transfer and to decrease recombination processes. Investigations of Y6‐containing active layers by atomic force microscopy (AFM) and high‐resolution transmission electron microscopy (HR‐TEM) show the presence of fibers, which highlights the assistance of Y6 in the nanostructuration of the blends. The higher PCE of the TOSC is explained with larger values of short‐circuit current density ( J SC ) from a broader absorption range and a superior value of fill factor (FF) supported by the faster mobilities and more balanced µ e / µ h . This work spotlights the beneficial role of the two acceptors in the TOSC. It explains the achievement of the highest average PCE of 16.0% for [Pt] polyyne oligomers to this date.

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.
