Dye-sensitized Solar Cell Based on Composite Poly(ethylene oxide) Electrolyte with Natural Carmine Pigment

Carmine particles which were prepared by precipitating natural cochineal extract with tin ions were incorporated into a solid-state composite poly(ethylene oxide) electrolyte (CPE). The conductivity of the modified CPE as calculated from the electrochemical impedance spectra, was increased with incr...
