Wave-optical studies of light trapping in submicrometre-textured ultra-thin crystalline silicon solar cells
Bibliographic record
Abstract
Wave optics calculations are performed to determine the energy conversion efficiency of pyramidal textured thin c-Si solar cells. For an optimized 20 µm thick c-Si device backed by a silver mirror an efficiency of 21.3% is obtained. An alternative approach to back reflection, submicrometre phase-shifted pyramid texturization on the back surface instead of the lossy metal mirror is demonstrated to yield a higher efficiency of 21.5%. More significantly the phase-shifted texturization approach permits light to enter the solar cell from both the front and back surfaces. For 10 µm and 5 µm thicknesses, efficiencies of 20.4% and 19.0% are obtained, respectively. Thus, the architecture is amenable to fabrication of high-efficiency ultra-thin bifacial solar cells.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
