Optical characterization of selectively transparent and conducting photonic crystals for use in thin crystalline silicon photovoltaics
Bibliographic record
Abstract
The potential use of selectively transparent and conducting photonic crystals (STCPCs) made of ITO and silica nanoparticles as rear reflectors in 10 μm crystalline silicon (c-Si) photovoltaics (PV) have been explored. Optical simulations comparing the performance of STCPC-reflectors and aluminum reflectors have been performed. The STCPCs outperform aluminum reflectors deposited on the crystalline silicon surface, but exhibit significantly lower reflectivity than the case where a substantial silica film layer is included between the aluminum reflector and the c-Si absorber. However, solar cells using STCPCs as the rear-reflector are capable of generating a significant amount of photocurrent from rear illumination in bifacial PV. An STCPC has been fabricated on a 10 μm c-Si membrane and the reflection and transmission spectral measurements demonstrate the expected increase in absorption in the red-to-NIR range.

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.
