Abstract
The cobalt complex [Co(2,2′-bipyrimidine) 3 ](PF 6 ) 2 ( Co-bpm ) was tested as a redox mediator in the dye-sensitized solar cell. The measured photovoltages for the cells were in excess of 1 V, which is approximately 3-fold greater than that measured for devices where [Co(2,2′-bipyridine) 3 ](PF 6 ) 2 ( Co-bpy ) was used as the redox mediator under the same experimental conditions. The root cause of this voltage enhancement is the Co III /Co II redox potential for Co-bpm being positively shifted by 0.50 V relative to the Co-bpy mediator. This result highlights how the number and position of the N atoms in aromatic ligands can have a profound effect on the measured photovoltage.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
