• excitation since its photon quantum energy is in resonance with excitons in ZnS single crystals. The emission was analyzed in a quasi-backscattering geometry through a double SDL-1 spectrometer. The signal from a FEU-106 photomultiplier with SbKNaCs photocathode working in a photon counting mode was fed to a

• indicating the stoichiometric ratio of 1:2. We propose that a semitransparent Co3O4 photoactive electrode is a prospective candidate for use in PEC cells via heterojunctions for hydrogen generation.

• RHE, and the operation of the photocathode. The value of the onset potential (Von), which is the condition attributed to a minimum charge transfer of the cell, was found to be just below that of the OER potential. All of the Co3O4 samples exhibited a photoresponse, suggesting photoabsorption and the

Next, the current–time characteristics of the 170 nm thick semitransparent Co3O4 photocathode were studied in transient light as shown in Figure S1 (Supporting Information File 1).

Compared with the hydrogen evolution at the semiconductor photocathode, the low efficiency of oxygen evolution at the photoanode poses a great challenge to the water splitting process [5]. As a result, great efforts have been made in
