Photoelectrochemical Properties of Chemosynthesized CdS Thin Film

Thin film of cadmium sulphide (CdS) consisting cabbage like morphology was chemically synthesized at room temperature from an aqueous alkaline bath onto soda lime glass and fluorine-doped tin oxide (FTO)-coated glass substrates. The synthesized cabbages of CdS were characterized using X-ray diffraction (XRD), UV-vis spectroscopy and scanning electron microscopy (SEM). The XRD pattern revealed the formation of CdS particles with a cubic crystal structure. SEM micrographs show that the cabbage like morphology is composed of nanopetals. Further, the photoelectochemical (PEC) performance was tested in Na2S-NaOH-S electrolyte which has maximum short circuit current of (Isc) 359 mu A/cm(2).
