Abstract
Long term power loss due to cell cracks can become a significant PV wear out mechanism. An experimental framework to assist in predicting the power loss from cell cracks during module service life is presented. The paper is primarily structured around cell crack origin in laminated modules, crack orientation, oriented crack reproduction and climatic testing of custom mini-modules. The results are experimentally verified by a series of accelerated tests involving mechanical load and humidity freeze tests. Periodic characterization using EL and flash I-V are used to study evolution of crack types/categories and performance loss due to cell cracks. Manufacturing modules cell crack data was collected from a population of a week of data post lamination. The data analyzed is for a certain batch of polycrystalline cell modules. Jabil has produced few GW of modules over the past years.

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
