Abstract
Both electrodeposition and performance assessment of new photocathode design are carried out using cuprous oxide for solar hydrogen production. The maximum delivered light can be collected using the mesh dome design of the photocathode, and the light can also reach the farthest photocathode surfaces via the mesh shape. The stainless‐steel mesh dome electrode is coated with cuprous oxide using the electrodeposition method. This photocathode is examined in an alkaline electrolyte solution of potassium dioxide for hydrogen production. Two light angles are studied to explore the effects of the new photocathode design on the hydrogen yield rate and associated energy and exergy system efficiencies during the daytime, where the light angles change. The maximum hydrogen production rates are generated experimentally at 0.1 m KOH at the 45° tilt light, and vertical light positions are 5.13 and 5.58 μg s −1 , respectively. Moreover, the highest exergy and energy system efficiencies are 0.82% and 1.18%, respectively, under vertical light, while they are 0.75% and 1.09% under tilted light conditions. The improvement of hydrogen production rates at tilted light can reach around 75.6% of the enhancement by vertical light due to the new photocathode design.

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 it
