LOW COST CARBON CATHODE FOR NATURAL DYE SENSITIZED SOLAR CELL
Keywords:Dye sensitized solar cell, TiO2 nanoparticles photo anode, carbon cathode, eosin Y dye
Objective: Platinum film on fluorine doped tin oxide (FTO) glass surface has been used commonly in the research of dye sensitized solar cells (DSSCs). However, cost of platinum is too high to fabricate a cost effective ecofriendly DSSC. The current study has been done to replace the high cost platinum counter electrode by low cost carbon electrode.
Material and Method: TiO2 nanoparticles has been synthesized and used to synthesize Photo anode of DSSC on fluorine doped tin oxide (FTO) glass surface. Platinum and Carbon cathodes has been synthesized on fluorine doped tin oxide (FTO) glass surface fabricated and their photovoltaic properties have been compared. Area of the cathode and anode has been maintained 1square centimeter.
Results: Study of DSSCs reveals, carbon cathode can successfully replace the platinum cathode as efficiencies of DSSCs have been found to be more using carbon cathode as compare to the platinum cathode. Ecofriendly Eosin Y dye sensitized TiO2 nanoparticles photo anode has been used for the fabrication of DSSC.
Conclusions: Investigation leads to the conclusion that carbon cathode can replace the platinum cathode in dye sensitized solar cell.
