Abstract
The temperature and intensity dependence of the limiting efficiencies of monofacial and bifacial silicon solar cells are calculated from the physical properties of silicon assuming light trapping by Lambertian scattering from rough surfaces. The maximum efficiency of a bifacial cell (28.92%) is lower than the efficiency of a monofacial cell (29.46%) at room temperature and Air Mass 1.5 Global illumination. The effects of electron-electron interactions on the band gap, radiative recombination rate, and optical absorption are included self-consistently. The temperature coefficient of the output power is -0.23%/°C for the optimum thickness monofacial cell at room temperature. The optimum thickness of silicon solar cells decreases strongly with temperature following a power law T <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-7</sup> and thin cells have a lower temperature coefficient than thick cells. A surface recombination velocity of 1 cm/s is found to be a turning point below which surface recombination has a small effect on the 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
