1. A method of manufacturing a conductive polymer thin film, comprising:
a step of coating a substrate with a first dopant solution comprising a polymer material and a first dopant to form a first conductive polymer thin film subjected to first conductive treatment; and
a step of performing second conductive treatment using a second dopant solution comprising pyronin B on the first conductive polymer thin film to form a second conductive polymer thin film, wherein conductivity of the second conductive polymer thin film is higher than that of the first conductive polymer thin film, and
wherein the pyronin B separates phases of the polymer material to induce connection between grains.
