Abstract
Three photoelectrochemical devices, developed at Simon Fraser University, employing electrochemically deposited cadmium selenide photo-anodes, a polysulphide redox'electrolyte and an in situ energy storage com-partment were evaluated at DREO. The photoelectrochemical devices were initially tested using tungsten filament lamps, and the evaluation was com-pleted with a xenon lamp which closely matched a solar spectrum corresponding to AM1 (air mass 1) conditions having an irradiance level of 889 Wm-2. V4 Maximum power output of the devices was in the 10-20 mW range-re- _ _ sulting in a solar (AM1) to electrical conversion efficiency of < i%. A fill-factor approaching 0.25 was typical for the photoelectrochemical cells examined. Counter electrode polarization and electrolyte light absorption were identified and evaluated as efficiency limiting factors. Proposed loss mechanisms are: series resistance In the semiconductor bulk, electron tunnel-q • ing to surface states, current carrier losses at electron-hole recombination.-

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
