Abstract
Carbon quantum dots (CQDs) have recently emerged as viable alternatives to traditional semiconductor quantum dots because of their facile and low cost synthesis, long term colloidal stability, and low environmental and biological toxicity. The compatible surface chemistry, good solubility in polar solvents and extensive optical absorption throughout the visible and near-infrared wavelength regions render CQDs as potentially useful sensitizers for photovoltaic applications. Presented herein is a new strategy for the solution phase synthesis of water-soluble, colloidally stable CQDs and a preliminary exploration of their utilization as sensitizers in nanocrystalline TiO2 based solar cells. Under AM 1.5 illumination, the Voc and FF values reach 380 mV and 64% respectively, achieving a power conversion efficiency of 0.13%.

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
