Fabrication and conductivity of thin PEDOT: PSS-CNT composite films
In this work, two methods for fabrication of composite conductive films, consisting of single walled carbon nanotubes (SWCNTs) and PEDOT:PSS, in order to obtain films with high conductivity and transparency for their use in solar cell structures based on Si have been compared.

| Summary: | In this work, two methods for fabrication of composite conductive films, consisting of single walled carbon nanotubes (SWCNTs) and PEDOT:PSS, in order to obtain films with high conductivity and transparency for their use in solar cell structures based on Si have been compared. The thickness and optical parameters of the films were determined using the spectro-ellipsometric measurements within the spectral range 0.6…5.0 eV. The electrophysical parameters were obtained from the four-point probe measurements. Our results showed that the method for deposition of SWCNTs and PEDOT:PSS in layers enables to obtain films with a much higher conductivity (220…306 S/cm) as compared to the method of applying a film from their mixture (6…209 S/cm). |
