Figure Lengend Snippet: (A) Current–potential curves for photocathodes prepared from Au/CdTe/CdS/Pt, Au/ZnTe/CdTe/CdS/Pt, and Au/Cu/ZnTe/CdTe/CdS/Pt (RTA). (B) HC–STH curves calculated from the current–potential curves for Au/CdTe/CdS/Pt, Au/ZnTe/CdTe/CdS/Pt, and Au/Cu/ZnTe/CdTe/CdS/Pt (RTA). Measurements were conducted under chopped simulated sunlight in a 1 M aqueous KPi solution whose pH was adjusted to 6.5. The applied potential was swept at +10 mV s −1 .

Figure Lengend Snippet: (A) Hydrogen and oxygen evolution and (B) time course of the photocurrent for the Au/Cu/ZnTe/CdTe/CdS/Pt (RTA) photocathode under simulated sunlight in a three-electrode configuration with an applied potential of 0 V RHE . The expected amounts of hydrogen and oxygen (denoted as e − /2 and e − /4, respectively), as calculated from the observed photocurrent, are shown as dashed lines. A 1 M aqueous KPi solution whose pH was adjusted to 6.5 by addition of KOH was used as the electrolyte. The photoelectrode area was 0.488 cm −2 .
