Study of the effect of the doped poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) polymeric anode on the organic light-emitting diode performances

► Doped Poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate) is proposed as anode. ► Transparent and conductive polymeric anode is used in organic light-emitting diodes. ► Efficiency of polymeric anode device is comparable to device with indium tin oxide. ► Lower optical switch-on and higher luminance are observed. ► Interface state density is modified by addition of the dopant in polymeric electrode.
