Abstract

The photoelectrochemical (PEC) properties of nanoflake-like cadmium sulfide (CdS) sensitized zinc stannate (Zn₂SnO₄) heterostructure prepared by spray pyrolysis technique and chemical bath deposition (CBD) are investigated in detail. The crystallinity and surface morphology of the Zn₂SnO₄ and CdS films are evaluated by X-ray diffraction (XRD), and scanning electron microscope, whereas its optical properties are analyzed by UV-VIS spectroscopy. Zn₂SnO₄ exhibits uniform granular structure and it has well defined reflection along (311) plane revealing inverse-spinel cubic structure. Zn₂SnO₄ showed band gap of 3.8 eV, it is well agreeing with the literature. The CdS films fabricated by CBD exhibited nanoflake-like structures. The XRD pattern of the CdS-sensitized Zn₂SnO₄ heterostructure exhibits a mixed phases of the zinc stannate and CdS. The PEC properties of the Zn₂SnO₄-CdS heterojunction are studied by using a three-electrode electrochemical cell in a Na₂S electrolyte. Zn₂SnO₄-CdS system has shown 0.8 mA/cm² photo-current density whereas with increasing CdS layer thickness it has shown marginal enhancement up to 2.2 mA/cm². The stability of the Zn₂SnO₄-CdS heterojunction is outstanding up to 300 s. The results demonstrate that Zn₂SnO₄-CdS heterojunction could be a potential material in PEC and solar cell applications.
