The hybrid material (CP-25) displays a conversion efficiency of 7.16% compared to 7.30% for the standard Pt counter electrode, 4.48% for bulk PEDOT and 5.56% for CNF. The enhanced conversion efficiency of CP-25 is attributed to the accomplishment of high conductivity and surface area of PEDOT through the 1-D alignment compared to its bulk counterpart. Reduced charge transfer resistance and high conductivity of CP-25 could be proven by cyclic voltammetry, impedance analysis and Tafel experiments. Further, through a long-term stability test involving efficiency profiling for 20 days, it is observed that CP-25 possesses excellent durability compared to the bulk PEDOT.</p>1 aAnothumakkool, Bihag1 aGame, Onkar, S.1 aBhange, Siddheshwar, N.1 aKumari, Tanya1 aOgale, Satishchandra, B.1 aKurungot, Sreekumar  uhttps://library.ncl.res.in/content/enhanced-catalytic-activity-polyethylenedioxythiophene-towards-tri-iodide-reduction-dsscs-0
