Wavelength dependent IPCE performance of the AuTiO2/PbS/CdS and TiO2/PbS/CdS photoanodes. Optical absorption of AuTiO2/PbS/CdS photoanode is also plotted for correlation between IPCE and light absorption. Inset shows the IPCE enhancement of AuTiO2/PbS/CdS over TiO2/PbS/CdS. An enhancement factor of 1.7–2 was observed over the entire absorption regime reiterates the active PIRET role in improving the current and HER. Integrated current obtained from IPCE for both photoanodes are also given.
