Abstract: A simple method of successive ionic layer adsorption and reaction (SILAR) was employed to prepare SnS sensitized nanocrystallite TiO2 photoanodes. The characteristics of these photoanodes, such as surface morphology, crystal structure, UV-Vis adsorption and diffusion properties, were measured with XRD, TEM, UV-Vis adsorption and diffusion spectra, respectively. The photovoltaic performances of SnS sensitized solar cells with these photoanodes were measured. The effects of counter electrodes with polyaniline or platinum catalyst and liquid electrolytes with iodine or sulfur redox couple on the photovoltaic performance were also studied. The cells assembled with these different components showed different photovoltaic performance. It was found that the cell assembled with the photoanode fabricated by 9 times of SILAR circulation, the counter electrode with polyaniline-stainless steel net, and the liquid electrolyte containing sulfur redox couple showed the highest photovoltaic performance. The short-circuit current density, open-circuit voltage, fill factor, and power conversion efficiency could reach 4.59 mA/cm2, 0.547 V, 0.505 and 1.27%, respectively.
