Title: Organic–inorganic heterojunctions for optoelectronic applications
Abstract: Various properties of different optimized organic solvents and graphene oxide-doped poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) films, PEDOT:PSS/Si heterojunctions, and solar cells have been studied in detail. The conductivity of PEDOT:PSS films was enhanced by three orders of magnitude with graphene oxide whereas all films remain highly transparent (>85%) in the visible region. The partial removal of PSS and the formation of conducting PEDOT-connected networks contribute to the enhanced electrical conductivity of PEDOT:PSS films. The removal of PSS was also confirmed by CAFM measurements. Solar cell fabricated with ethylene glycol-doped PEDOT:PSS film showed a maximum power conversion efficiency as compared to other solvents-doped PEDOT:PSS film. The highly conducting and transparent material can be used in various future optoelectronic devices.
