Figure 1

(a) Schematic structure of the surface-protected photocathode showing photon absorption and generation of an electron-hole pair in the p-Cu2O. The extraction of the excited electron through the TiO2-protective layer to produce hydrogen on the MoS2+x catalyst is also illustrated. (b) A digital image of a MoS2+x-CA-Cu2O photocathode. Scale bar, 5 mm. The area covered with the MoS2+x catalyst (66 μg cm−2) is in the middle of the photoelectrode and corresponds here to 0.48 cm2.
