Abstract

fetched live from OpenAlex

Abstract Anisotropic carrier transport and deep‐level defect of antimony selenosulfide (Sb 2 (S,Se) 3 ) absorber are two vital auses restraining the photovoltaic performance of this emerging thin‐film solar cell. Herein, chelate engineering is proposed to prepare high‐quality Sb 2 (S,Se) 3 film based on hydrothermal deposition approach, which realizes desirable carrier transport and passivated defects by using tetrahedral PO 4 3− ion in dibasic sodium phosphate (Na 2 HPO 4 , DSP). The PO 4 3− Lewis structure, on one hand in the form of [(SbO) 3 (PO 4 )] chelate, can adsorb on the polar planes of cadmium sulfide (CdS) layer, promoting the heterogeneous nucleation, and on the other hand, the tetrahedral PO 4 3− inhibits horizontal growth of (Sb 4 S(e) 6 ) n ribbons due to size effects, thus achieving desirable [hk1] orientation. Moreover, the introduction PO 4 3− effectively passivates the antisite defect Sb S1 . These synergistic effects have effectively improved carrier transport and reduced non‐radiative recombination of the Sb 2 (S,Se) 3 absorber. Consequently, the DSP‐modified Sb 2 (S,Se) 3 device efficiency increases from 8.59% to 10.67%.

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.
