Black line: Incident photon‐to‐current efficiency (IPCE) spectrum of LTCA|TiO2|NiP photocathode in pH 3 Na2SO4 (0.1 m) electrolyte solution irradiated with a 300 W Xe lamp fitted with narrow band filters under a purge of Ar and an applied potential of 0.3 V vs. RHE. Red dashed line: DRS UV/Vis spectrum of LTCA powder (in Kubelka–Munk absorbance units).
