Two-dimensional modeling of CdZnTe/Si based dual and triple junction solar cells
Bibliographic record
Abstract
Based on Crosslight APSYS, we have made 2D simulation of dual and triple junction solar cells based on CdZnTe and CdTe material system on Si substrate with tunnel junctions. The basic physical quantities like band diagram, optical absorption and generation for these solar cells, and external quantum efficiency for individual subcell junctions of triple junction solar cells are obtained. Current matching analyses and multi-sun concentration simulation are also performed. The modeling shows efficiency 28.85% (one sun AM1.5G) for CdZnTe/Si dual junction solar cells and efficiency 34.92% (one sun AM1.5G) and maximum 39.09% (multi-sun concentration around 500-700 suns) for CdZnTe/CdTe/Si triple junction solar cells. The presented results indicate that the dual and triple junction solar cells with II-VI CdZnTe and CdTe on Si can achieve efficiency comparable to those III-V based compound on Ge substrate.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
