Nanocomposite organic/inorganic compounds are used to fabricate thick, conductive and highly transparent layers, which are used as hole injection and transport layers in OLEDs. The composite layers consist of SiO 2 ‐nanoparticles and the polymer PEDOT:PSS. The filling fraction of PEDOT:PSS in these thick layers is reduced to 3.9%. OLEDs comprising such composite layers show an increased outcoupling efficiency.
