Abstract
Cu 2 ZnSnS 4 (CZTS) nanocrystals were synthesized via a one-pot method and photoelectrochemical measurements (PECMs) were used to quantitatively compare CZTS films. Based on their initial metal stoichiometry and photoresponse behavior, CZTS films were divided into groups of high-photoresponse (hp-CZTS) and low-photoresponse samples (lp-CZTS). An X-ray absorption near-edge structure (XANES) study was then performed to unravel the origin of the difference in their photovoltaic properties. The results demonstrated that the local structures of the elements and their interaction with capping ligands are different and strongly affect the photovoltaic behavior, although both CZTS groups through one-pot synthesis were free of secondary phases. It was determined that the coordination of Zn and the capping ligand–metal interaction are the two major factors for the production of higher photocurrent. The correlations will guide us to produce viable CZTS films crucial for the development of solar energy conversion.

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
