Electrical characteristics of semiconductor polymer films doped with silver nanoparticles

Abstract

The electrical properties of composite films based on polymer PEDOT:PSS with а addition of Ag nanoparticles or Ag–TiO2 nanostructures have been studied. A current–voltage characteristic is observed for polymer solar cells. A short circuit current increased after adding of Ag nanoparticles or Ag–TiO2 nanostructures to the PEDOT:PSS polymer. Also, an increase in the recombination rate in cells with silver nanoparticles is observed. An electrical impedance is measured for polymer solar cells. A significant increase in the dielectric constant of a PEDOT:PSS film containing silver nanoparticles was detected.
