Relationship between Morphology and Electrical Properties of PEDOT:PSS Films Used as Anode in Organic Solar Cells

In this paper, the conductivity of PEDOT:PSS films prepared on glass has been investigated by a four-point-probe resistivity system. In the next step, to study the impact of annealing time on conductivity enhancement, films were annealed at different time. After annealing of the PEDOT:PSS film, the conductivity of thin layer increased. The effect of annealing on surface morphology and topography changes was studied using Atomic Force Microscopy (AFM). AFM images showed that the heat treated PEDOT:PSS caused to better pathways for charge transport in films and thus the conductivity of this layer increased.
