Abstract

fetched live from OpenAlex

The key effects of adding quantum dots in the middle sub-cell of a lattice matched triple junction solar cell are studied as a function of concentration in an advanced numerical simulation environment. The quantum dots are modeled using an effective medium which contains a quantum mechanical absorption coefficient, quantum dot to bulk carrier dynamics and minority carrier lifetimes. In the presented study, we report a change in efficiency between −0.2% and +0.8% for the QD enhanced design relative to the control design at 1 sun and an efficiency increase between +0.1 % and +1.2% at 1000 suns. The difference in this behavior over concentration for the different designs is predominantly due to an increase in overall recombination rates in the intrinsic region of the middle sub-cell.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
