The effect of photon recycling on thermophotovoltaic systems
Bibliographic record
Abstract
Abstract: Thermophotovoltaic (TPV) systems are optical heat engines that directly convert radiant heat from an emitter into electricity using a photovoltaic (PV) cell. TPV is a versatile technology that can convert heat from any high temperature source (>1000 K) into electricity. Recently, TPV systems have achieved greater than ~40 % conversion efficiencies and are emerging as a promising method for grid energy storage and combined heat and power for the industrial and residential sectors in decarbonized energy systems. However, the efficiency of TPV systems is still low compared to their maximum theoretical efficiency and is often limited by the operating temperature of their emitter. For example, according to Planck’s law, for a TPV system with a blackbody (BB) emitter and GaSb PV cell (Eg = 1.72 ?m), increasing the temperature of the emitter from 1500 K to 1650 K (10% increase) results in a 94% increase in the number of photons with energy above the bandgap energy of the PV cell which can be converted into electricity.

How this classification was reachedexpand
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.
