Interfacial Structure Modifying Interlayers Equalize Substrate Performance: The Case of PEDOT:PSS

Variability of indium tin oxide properties can be a significant concern for wide-scale manufacturing of organic devices. Many treatments and interlayers have been proposed to optimize the electrode surface for high device performance. One of the proposed mechanisms is smoothing of the anode to achieve better interfacial contact with the active layers. To examine the impact of substrate roughness on the structure, morphology, stability and …
