Zeolitic-imidazolate-framework (ZIF-8)/PEDOT:PSS composite counter electrode for low cost and efficient dye-sensitized solar cells

ZIF-8 polystyrenesulfonate-doped poly(3,4-ethylenedioxythiophene) (ZIF-8/PEDOT:PSS) is prepared and used as the alternative counter electrode (CE) for dye-sensitized solar cells (DSSCs) based on I⁻/I₃⁻ and Co²⁺/Co³⁺ redox mediators.
