Abstract
The standard module cell interconnection technique requires printed Ag front side busbars and rear side Ag/Al pads. From the standpoint of cell performance these contacts reduce cell efficiency strongly as a result of large cell shading and reduced surface passivations. Cells without busbars and pads would show a cell current and voltage increase and simplify the printing procedure. In this paper we introduce a new cell metallization technique which could be directly applied to standard industrial cells eliminating the need for rear pads and front busbars. Experiments were carried out to study the current and voltage gain of modified cells with the proviso that the cell fill factor will maintain at high level. Optimization experiments showed up to 0.8% higher cell efficiency for modified cells if compared to reference cells. Technique was furthermore successfully applied to 8 inch cells which showed fill factors of 77.9%

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
