Abstract

This work presents the results of a study of the morphological, optical, and electrophysical parameters of Nickel Oxide/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (NiO/PEDOT:PSS) composite films. It is shown that an increase in the speed of rotation of the substrate leads to a decrease in the surface roughness of NiO films. As the surface roughness of the Nickel oxide decreases, the roughness of the PEDOT:PSS film also decreases. Increasing the speed of rotation of the substrate leads to a decrease in the optical density of the absorption spectra of NiO films, as well of composite films NiO/PEDOT:PSS. It was found that changes in the morphology of NiO/PEDOT:PSS composite films contribute to the rapid transport of injected holes to the external electrode and reduce the probability of reverse recombination.
