摘要
Graphite nanopowder is synthesized by mechanical method using ball mill and used as filler in polymer electrolyte film based on Polyvinyl alcohol(PVA)for application in natural dye sensitized solar cell(DSSC).In the present work dye sensitized solar cell has been assembled using electrolyte system composed of PVA as host polymer,ethylene carbonate as plasticizer,LiI:I2 as redox couple and graphite as filler;TiO2 modified with Copper oxide(CuO)photoanode in order to provide inherent energy barrier and natural cocktail dye as sensitizer.The obtained solar cell conversion efficiency was about 3.2%with fill factor 52%using an irradiation of 100 mW/cm^(2) at 25℃C.
