Zinc sulphide photoanode was prepared by a cost-effective and simple successive Ionic layer adsorption and reaction (SILAR) process on to a fluorine doped tin oxide (FTO) substrate for photoelectrochemical solar cell application. From the optical absorption spectrum, a bandgap of synthesized ZnS photoanode was obtained around 3.47-3.62 eV. The surface morphology of the deposited photoanode was characterized using field emission scanning electron microscopy (FESEM). The average thickness of the deposited film was found to be 2.25 µm. We have fabricated photoelectrochemical solar cells using low crystalline ZnS as photoanode material and Coumarin-343 (C-343) dye as a sensitizer. photoelectrochemical solar cells have been built and their photocurrent, open-circuit voltage, fill factor and efficiency has been measured under one sun. Nyquist plot and Bode plot were plotted using electron impedance spectroscopy (EIS). The effective parameters were found. The photovoltaic properties of the ZnS based photoelectrochemical solar cell were studied. The maximum efficiency of 0.1% was observed for ZnS based photoelectrochemical solar cells.
