“…The inset of Fig. 1 shows the absorption peak at 225 nm, attributed to absorption from the phenyl rings in the PSS [31]. A similar absorption peak was seen for both PEDOT:PSS UT and PEDOT:PSS ADD electrodes, but a large decrease was observed for the PEDOT:PSS IMM electrodes.…”

“…5C). This electronic transition has been observed in doped PEDOT (34), indicating the existence of a highly conductive phase in solutionsheared films. This indicates that the solution shearing deposition process, while better allowing the removal of excess PSS near the surface, also maintains the potency of the remaining PSS dopants.…”

With consumer electronics transitioning toward flexible products, there is a growing need for high-performance, mechanically robust, and inexpensive transparent conductors (TCs) for optoelectronic device integration. Herein, we report the scalable fabrication of highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) thin films via solution shearing. Specific control over deposition conditions allows for tunable phase separation and preferential PEDOT backbone alignment, resulting in record-high electrical conductivities of 4,600 ± 100 S/cm while maintaining high optical transparency. High-performance solution-sheared TC PEDOT:PSS films were used as patterned electrodes in capacitive touch sensors and organic photovoltaics to demonstrate practical viability in optoelectronic applications.transparent conductor | solution shearing | PEDOT:PSS

“…It has been observed that the conductivity increases when certain organic solvents has been added to a PEDOT:PSS water solution [12]. Some examples are dimethyl sulfoxide (DMSO), N,Ndimethylformamide (DMF) [13], glycerol, sorbitol [14][15] and ethylene glycol [16].…”

The electronic structure and reflectivity of PEDOT:PSS from density functional theory

The geometric and electronic structure of condensed phase organic conducting polymer PEDOT:PSS blends has been investigated by periodic density functional theory (DFT) calculations with a generalized-gradient approximation (GGA) functional, and a plane wave basis set. The influence of the degree of doping of the PEDOT polymer on structural and optical parameters such as the reflectivity, absorbance, conductivity, dielectric function, refractive index and the energy-loss function is studied. A flip from the benzoid to the quinoid structure is observed in the calculations when the neutral PEDOT is doped by negatively charged PSS. Also the optical properties are affected by the doping. In particular, the reflectivity was found to be very sensitive to the degree of doping, where higher doping implies higher reflectivity. The reflectivity is highly anisotropic, with the dominant contribution stemming from the direction parallel to the PEDOT polymer chain.
