Best Paper Award for the paper presented on “Comparative study of electrolytes used in the synthesis of cocktail dye based dye sensitised solar cell” in International Conference on Energy and Infrastructure Management ICEIM, on 15-16 February 2018 organised by School of Petroleum Management, Pandit Deendayal Petroleum University.

Abstract: The solar cells have been into existence since the nineteenth century which were mostly dependent on silicon for their production; but at the advent of twentieth century with anthracene showing photoconductivity another class of solar cells originated—which were the third generation solar cells or say Organic Solar Cells. One of these solar cells is dye sensitized solar cells (DSSCs), which came into existence in the latter half of the twentieth century and since then have flourished and have reached quite a satisfactory power production on the lab scale. Considering the series of events, here two dyes of natural origin with photosensitizers Betalain and Chlorophyll extracted from Beetroot and Spinach respectively have been discussed briefly. The comparison of electrolytes which are three in number, listed as: KI/I2 redox couple, suspension of Polyaniline (PANI) and an amalgamation of these two is done. Since natural dyes are used in a totally new approach, so the overall cost reduces and the efficiency with respect to only natural dyes increases thereby helping in stable energy storage.
