Compound semiconductor GeSe nanosheet-based thin films were systematically researched for application in solar water splitting. p-type GeSe films obtained from the rapid thermal sublimation method have a sheetlike grain structure and a homogeneous elemental distribution, which is suitable for application in photocathodes for solar hydrogen production. Deposition of a CdS layer on top of GeSe was found to be effective in enhancing the photoelectrochemical properties due to the p–n junction formed at the interface of CdS/GeSe that enhances the separation rate of photoexcited carriers. Furthermore, the atomic layer deposition of the TiO2 overlayer under the CdS/GeSe photocathode not only protects the CdS from photocorrosion but also reduces surface recombination, which could generally enhance photocathode performance. The obtained Pt-TiO2/CdS/GeSe photocathode generated ∼10.5 mA/cm2 under 0 VRHE and presented an onset potential of ∼0.45 VRHE. The calculated half-cell solar-to-hydrogen (HC-STH) efficiency of ...
