FABRICATION AND CHARACTERIZATION OF NATURAL DYESENSITIZED SOLAR CELLS BASED ON PbS NANOSTRUCTURES

Natural dye-sensitized solar cells were fabricated based on differently shaped Lead Sulfide nanoparticles in a simple cost-effective way. The grown PbS nanoparticles were characterized by TEM, XRD, Optical Absorption, and Photoluminescence study. The natural dye-sensitized solar cell was fabricated using a kind of dye from Clitoria ternatea as a sensitizer. The current-voltage data of the dye-sensitized solar cell was taken under dark and light illuminated conditions. The dye-sensitized solar cell efficiency was measured and the ideality factor, fill factor were also found out. The open-circuit voltage and short circuit current density of the dye-sensitized solar devices based on three different shaped PbS nanoparticles are also obtained and compared.
