Abstract
High concentration reduces the per-Watt cost of high-efficiency tandem cells to below that of silicon PV cells, but traditional High-Concentration PV (HCPV) has been burdened by high optics, receiver, and balance-of-module costs. Trough/Lens/Cone optics can achieve very high concentration with low-cost optics, and the three optical stages provide numerous opportunities for optimizations to reduce overall module cost and energy cost. This paper explores the main optics trade-offs and the resulting optimizations and their impact on module cost and Levelized Cost of Energy (LCOE). The analysis indicates that with proper optimizations, this design can beat silicon PV on cost as well as on efficiency.

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
