Аннотация:A comparative study of the effect of graphene admixture to polyaniline holeinjection layers of
polymer light emitting diodes (PLEDs) and anode buffer layers of organic solar cells (OSCs) has been performed. The layers have been made from the complex of polyaniline with poly-2-acrylamido-2-methyl-1-propanesulfonic acid with (or without) addition of 1 wt % graphene prepared by the mechanochemical
method. It has been shown that the effects of the graphene addition into the auxiliary PLED and OSC layers
are opposite: performance characteristics (current and light efficiency) of the former deteriorate and those of
the latter are improved (in particular, the powerconversion efficiency increases by a factor of 1.4). The reasons
considered to be behind the opposite effects are a significant difference in the currents flowing through the
PLED and OSC, a more developed interface between the OSC anode buffer layer and photolayer, and channeling the longitudinal conductivity at the interface between graphene nanoparticles and polyaniline.
