The original version of this Article contained an error in the second sentence of the ‘Materials’ section of the Methods, which incorrectly read ‘PEDOT:PSS synthesized by Orgacon (739324 Aldrich, MDL MFCD07371079) was purchased as a surfactant-free aqueous dispersion with 1.1 wt% solid content.’ The correct version replaces this sentence with ‘PEDOT:PSS Orgacon ICP 1050 was provided by Agfa as a surfactant-free aqueous dispersion with 1.1 wt% solid content.’ This has been corrected in both the PDF and HTML versions of the Article.
