Virtual prototyping and optimization of novel solar cell designs
Bibliographic record
Abstract
Nano-scale structures have been proposed as a low cost mechanism to enhance solar cell efficiency. Computer simulations can be used to rapidly and cheaply prototype and optimize these novel designs, however the simulations are challenging due to the geometric complexity, the highly dispersive materials, and the necessity of performing broadband simulations over the solar spectrum. We show how the finite-difference time-domain (FDTD) method in conjunction with particle swarm optimization (PSO) can be used to efficiently optimize these designs. We apply the method to two specific examples: thin film silicon plasmonic solar cells and photonic crystal organic solar cells. In each case, optical enhancements of approximately 15% can be achieved. The optimization requires a few hundred simulations which can be achieved in a few hours on a good workstation. Finally, we consider the steps necessary to perform combined optical and electrical simulations to fully characterize these devices.

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.
