Design of anti-reflection coating for spherical silicon photovoltaic devices
Bibliographic record
Abstract
Spherical silicon photovoltaic devices are bonded to flexible substrates to produce light-weight flexible solar modules. In order to maximize the conversion efficiency, the optical loss must be minimized. The concept of conventional anti reflection coating (ARC) does not directly apply to the spherical device due to different geometry. The optimum design of the ARC must maximize the optical power transmission from air to the Si crystal bulk. In addition to the refractive index and the thickness of the ARC, the power distribution on the exposed spherical surface, incidence angle dependent reflection, and multiple reflections at the spherical air-ARC and ARC-silicon interfaces also influence the ARC design. The effects of the spherical shape on the variations of the reflection are analyzed. It is shown that the optimum design is essentially different from the conventional ARC with uniform quarter-wavelength thickness. It is required that the design compensates the effect of variation of the incidence angle across the spherical surface. To achieve this, the thickness should have a zenith-angle dependence. Chemical vapor deposition techniques can potentially be employed for the deposition of the designed films.

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.
