Pulse electrodeposition of CuSbS₂ thin films: Role of Cu/Sb precursor ratio on the phase formation and its performance as photocathode for hydrogen evolution^§.

ABSTRACT: In this paper, we outline the development of stoichiometric chalcostibite, CuSbS₂ thin films, from a single bath by pulse electrodeposition for its application as a photocathode in photoelectrochemical cells (PEC). The Cu/Sb precursor molar ratio of the deposition bath was varied to obtain stoichiometric CuSbS₂ thin films. The optimized deposition and dissolution potentials were -0.72 V and -0.1 V vs saturated calomel electrode, respectively. The formation of CuSbS₂ was analyzed using different characterization tools. X-ray diffraction and Raman results showed the formation of the pure chalcostibite phase from a precursor bath with molar ratio Cu/Sb = 0.41. The heterostructure CuSbS₂/CdS/Pt was tested as a photocathode in the PEC. The energy posi
