Studies on photoelectrochemical (PEC) cell formed with SILAR deposited Bi2Se3–Sb2Se3 multilayer thin films

Nanocrystalline Bi2Se3–Sb2Se3 multilayer thin films were deposited by simple and less investigated successive ionic layer adsorption and reaction (SILAR) method onto glass- and fluorine-doped tin oxide (FTO)-coated glass substrate from aqueous solution. Characterizations such as XRD, surface morphology and optical absorption have been carried out for Bi2Se3–Sb2Se3 thin films onto glass substrates. The films deposited onto FTO-coated glass substrates were used to study photoelectrochemical behaviour in 0.1 M (NaOH–Na2S–S) electrolyte and results are reported.
