Synthesis and Characterization of Cadmium Sulfide Nanoparticles for the Applications of Dye Sensitized Solar Cell

F. Michael Raj, A. Jeya Rajendran

Cadmium sulfide nanoparticles were prepared by chemical precipitation method in aqueous medium using cadmium acetate and sodium sulfide. The synthesized nanoparticles were characterized by using UV-Vis studies, X-ray diffraction studies (XRD), field emission scanning electron microscopy (FESEM), energy dispersive x-ray analysis (EDAX) and BET analysis. The X-ray diffraction pattern revealed that the synthesized cadmium sulfide nanoparticles were polycrystalline nature and grain size 7 nm was calculated by using Scherer method. Specific surface area, pore volume and pore size were estimated by nitrogen adsorption-desorption analysis. The specific surface area of the synthesized material is 74.26 m2/g. The temperature and frequency dependence of dielectric constant, dielectric loss and AC conductivities were studied over a range of frequency (50 Hz to 5 MHz) and temperature (40 - 200°C). These results demonstrate that the CdS nanoparticles has a potential applications in DSSC’s.
