The synthesized highly porous PEDOT films exhibit room temperature conductivity value of 195 S cm(-1) along with reproducible high cycling life. These films were used as counter electrodes in dye-sensitized solar cells yielding similar to 8% power conversion efficiency, which is close to the classical platinum coated counter electrode (8.7%). The photovoltaic performance increases as we lower the PEDOT film thickness as the thin films has reasonably high catalytic properties.Carbon NanotubesLow-CostFilmsPoly(3,4-Ethylenedioxythiophene)TransparentPerformanceLightDye-sensitized solar cells based on poly (3,4-ethylenedioxythiophene) counter electrode derived from ionic liquidstext::journal::journal article::research article
