| Annotation |
Nanoparticles of zinc sulphide and cadmium sulphide are synthesized by aqueous chemical method. XRD data show cubic phase for both the systems. UV-Vis absorption spectra of nano ZnS and nano CdS are blue shifted from the respective bulk. The PL spectra of the above dye sensitized nanomaterials show two broad emission at 402 nm and 510 nm (absent in nano ZnS) which are compared with earlier investigations and discussed. The efficiency of dye sensitized nanocrystalline ZnS solar cell was found to be 0.09 % (Eosin Yellowish Dye) and 0.016 % (Methyl Blue dye). The efficiency of dye sensitized CdS was found to be 0.06 % and this makes it possible for improved efficiency. |
