Influence on the efficiency of dye-sensitized solar cell using Cd doped ZnO via solvothermal method

In this report, the transition metal Cd doped ZnO nanoparticles synthesized by solvothermal irradiation method was used to fabricate ZnO-based dye-sensitized solar cells as photo sensitizers of Terminalia catappa fruit using ethanol as solvent. These prepared metal oxide semiconductor nanoparticles were studied by XRD, FE-SEM, TEM, FTIR, UV-Visible, XPS and DC electrical conductivity. Electrochemical parameters of open circuit voltage, short circuit current density, and fill factor were calculated using J-V characterization. The effect of Cd doping on the efficiency of ZnO-based DSSC is investigated, which results in enhanced DSSC light harvesting efficiency calculated. This obtained result confirms that the doping of ZnO nanoparticles is a valuable material for increasing the corresponding efficiency of a solar cell application.
