Abstract
Doped hydrogenated silicon oxide layers (SiOX:H) have recently been successfully integrated as front window layers, back reflector layers, intermediate reflector layers, passivation layers, and junction layers in thin-film silicon solar cells. Depending on the deposition conditions of the SiOX:H layers, some devices suffer from a degradation in performance in time. In this paper, we demonstrate the responsible mechanism involved. It is demonstrated that oxidation of the p-type doped (p-)SiOX:H with a high crystallinity and, therefore, poor passivation of crystalline grains is responsible for this degradation. The oxidation of p-SiOX:H is caused by the in-diffusion of water vapor from the ambient air. Stable p-SiOX:H can be obtained if the material is processed at higher pressure. In addition, the degradation can be prevented if the cell is well encapsulated, like using dense n-type (n-)SiOX:H in the back reflector of the cell.

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
