PEDOT:PSS layers were prepared with three different additives. In particular, the conductivity effects of additives on PEDOT:PSS layers were examined depending on temperature. The conductivity values of PEDOT:PSS layers increase significantly with increasing temperature. These results confirm that PEDOT:PSS exhibits semiconductor properties. Additionally, there appears to be a significant difference, although not a vast difference between the conductivities of PEDOT:PSS for the three different additives. All these results show that both additives and especially temperature change the conductivities of PEDOT:PSS.
