Abstract
AbstractDye-sensitized solar cells (DSSCs) based on redox electrolyte solution set the limitation and restriction on its fabrication. Moreover, when this redox electrolyte comes in contact with photoanode causes its corrosion. The finding of ionic conductivity in polymer material complex with salt has given a breakthrough in the formation of DSSC devices. Polymer electrolytes, especially Polyvinylidene fluoride (PVDF), have attained considerable interest due to its some exceptional properties like thermal stability, chemical resistance, and excellent mechanical strength. In the present work, dye-sensitized solar cell has been assembled using electrolyte system composed of PVDF as host polymer, Ethylene Carbonate as plasticizer, LiI: I2 as redox, and couple and graphite as filler; TiO2 modified with CuO photoanode in order to provide inherent energy barrier and natural cocktail dye as sensitizer. The obtained solar cell conversion efficiency was about 2.27% with using an irradiation of 100 mW/cm2 at 25 °C.KeywordsDye-sensitized solar cellPolyvinylidene fluorideGraphiteCocktail dye
