Abstract
A two-dimensional, distributed resistance model for a four junction solar cell is implemented in SPICE. Efficiency estimates for Gaussian irradiance profiles with different peak-to-average ratios (PAR) are determined via grid optimization at concentrations of 500, 1000 and 2000 suns. Optimizing finger spacing for a PAR of 6 improves cell efficiency by 1.8% (absolute) at 2000 suns compared to that observed from finger spacing optimized for a uniform illumination. To address the impact of chromatic aberration on cell efficiency, a CPV system is modeled in Zemax for a geometric concentration of 1250X. Using a finger spacing optimized for uniform irradiance at the average optical efficiency of 82%, the neglect of chromatic aberration was found to overstate system efficiency by 3% (absolute).

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
