The LSV curves (a) of pristine TiO2, TiO2/CdS, and TiO2/PbS/CdS with chopped AM1.5 light illumination. The I–t curves (b) of pristine TiO2, TiO2/CdS, and TiO2/PbS/CdS at 0.9716 V vs. RHE under illumination. The energy level alignment (c) at the interface between PbS and CdS. The IPCE curves (d) of pristine TiO2, TiO2/CdS, and TiO2/PbS/CdS measured at 0.9716 V vs. RHE
