Symmetric photoelectrochemical behaviour of anion- and cation-doped polybithiophene
Abstract
Both anodic and cathodic photocurrents have been observed on a thin-film polybithiophene electrode and are dependent on the type of doping: anion-doped polymer feature cathodic photocurrents, while cation-doped polybithiophene demonstrate anodic photocurrents.
