Abstract

fetched live from OpenAlex

Based on the Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS), the specific surface and interface characteristics of emitter region of commercial mono-crystal Si solar cells were examined. Four chemical compositions C , O , Si , and P were detected, and the atomic concentrations (%) of C and O at the surface were much higher than their solid solubility in mono-crystal Si . The high concentration of C and O at the surface was attributed to adhered remains. The single element Si , stable oxide SiO 2, as well as intermediate oxidation states such as Si 1+ and Si 3+ corresponding to Si 2 O and Si 2 O 3, respectively, have been analyzed. The atomic concentrations (%) of these compositions and their respective chemical states at the surface and interface are likely correlative to the various defects such as electronic-like ramification of hanging bonds, vacancy cluster, or dislocations. Furthermore, the normalized quantum efficiency (QE) of the solar cells made from the wafers was measured to be lower than 74% at short wavelength (< 400 nm), and the influence of surface and interface states on the performance of solar cells was discussed.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
