The energy diagram of the PEC cell: the position of the conduction and valence bands of SnS thin film relative to the water oxidation and the water reduction potential (a). The digital photograph presented the phenomena of water splitting at 1.2 V versus RHE. (b) The working area of the electrode: 1 cm2.
