ABSTRACT = {This work used a sonication-aided approach to make Cadmium sulfide nanoparticles and 
Nitrogen-doped CdS nanoparticles. Doping Nitrogen into CdS NPs enhances the material's 
electrical, chemical, and structural properties by altering its surface area and functional 
sites. XRD, FTIR, SEM/EDX, TGA, UV-Vis, and PSA are used to evaluate the 
characteristic features of CdS NPs. The photovoltaic responses of the prepared CdS and 
CdS-N NPs were evaluated by electrochemical impedance and IV analysis. The obtained 
XRD data confirms that nitrogen doping significantly changes the crystal size of CdS NPs. 
The XPS spectrum depicts the presence of trace elements and confirms the nitrogen 
doping with CdS. The absorption spectra and band gap values derived from UV data 
demonstrate that nitrogen doping improves the optical characteristics of CdS NPs in the 
long run. CdS thin film photoanodes show improved photoresponse, even at such low bias 
voltages, according to the electrical characterisations.},
