Purpose: extract comparable evidence from a photoelectrochemical paper.
This is a literature-review record, not a laboratory procedure.

Paper / authors / date / experimental stage:
Semiconductor, interface, catalyst identity and attachment:
Illumination spectrum, intensity and calibration:
Electrolyte / pH / temperature:
Applied potential, reference electrode and external electrical input:
Area (cm2) and exact definition:
Photocurrent density (mA/cm2):
Total current = current density x area (mA):
Measured hydrogen quantity/rate, units, interval and calibration:
Faradaic efficiency and matching charge/gas intervals:
Solar-to-hydrogen efficiency definition and full-device boundary:
Starting/retained performance, elapsed time and interruptions:
Replicates / uncertainty / analysis after testing:
Strongest measured result:
Proposed interpretation and next evidence needed:

Fictional example: 10 mA/cm2 x 2 cm2 = 20 mA; 5 mA/cm2 x 10 cm2 = 50 mA. Current density and total current give different comparisons. Hydrogen output and energy efficiency require additional measurements.
