Copper ion doped ZnS quantum dots have been synthesized and introduced as sensitizer in solar cells. The quantum dots, synthesized using simple chemical method, has been characterized by using UV-Visible absorption spectroscopy, X-Rray Diffraction spectroscopy, and Trans-Electron Microscopy to study the influence of different concentrations of Copper ion doping on quantum dots. The successful doping is confirmed using Energy Dispersive X-Ray spectroscopic study. The Current density – voltage characteristics of the fabricated solar cells are studied and the photovoltaic parameters are compared for each cell. Better performance in terms of photo-conversion efficiency has been obtained for Cu ion doped ZnS quantum dot sensitized solar cells.
