The paper reports a detailed methodology for the preparation of polymer based dye sensitized solar cell (DSSC) using polyaniline (PANI). The cells were made using natural dye extracted from beetroot and indium tin oxide (ITO) coated glass. Three solar cells having different electrolytes were prepared and their efficiencies were determined. A mixture of conventional electrolyte (iodide and triiodide mixture) and HCl doped PANI have also been used and the results obtained from all the three cells were observed, compared and discussed. Ultraviolet spectroscopic results confirm the presence of dye extracted from beetroot and by the I-V curves, efficiencies of the cells calculated was 0.04694% (conventional electrolyte), 0.03170% (HCl doped PANI as electrolyte) and 0.02699% (conventional and PANI mixture as electrolyte).
