Previously, transition metal dichalcogenides (TMDCs) were studied as perspective candidates for photoelectrodes with efficiencies up to 17% upon illumination in acidic solutions using ntype single crystals. The high potential of such layer-type semiconductors (MoS 2 , MoSe 2 , WS 2 , WSe 2 ) is caused by their suitable bandgap energy in the range of 1-2 eV, a high absorption coefficient (~10 5 cm -1 ), and a long-term stability in an acidic electrolyte. TMDCs are strongly anisotropic materials which can be mechanically exfoliated into atomically thin X-Me-X slabs (where X = S, Se and Me = Mo, W). The strong crystallographic anisotropy manifests itself in anisotropic electrical transport properties since the electrical and thermal conductivity along the van der Waals (vdW) planes is by a factor of up to 100 higher compared to the transport perpendicular to the vdW planes. So far, it was not possible to transfer the results from small (mm 2 ) single crystal electrodes to large area (m 2 ) electrodes composed of polycrystalline, but highly oriented layers.
