“…Table 1 and Figure 4 shows this surface roughness dependence on WS2 nanoparticles concentration. 5 that the PEDOT: PSS film has a maximum at a wavelength of λ1 = 234.6 nm related to the absorption of PEDOT and a maximum at 278.2 nm associated with the absorption of the aromatic fragment of PSS [20,21,37]. When WS2 nanoparticles are added to the PEDOT: PSS solution, the optical density decreases and a slight bathochromic shift of the PEDOT absorption maximum is observed.…”

“…When WS2 nanoparticles are added to the PEDOT: PSS solution, the optical density decreases and a slight bathochromic shift of the PEDOT absorption maximum is observed. The observed long-wavelength shift of the PEDOT: PSS absorption maximum is associated with a change in the film structure due to the incorporation of WS2 nanoparticles between the PEDOT and PSS chains [3,21]. The impedance spectra were measured to study the effect of WS2 nanoparticles on electrotransport properties of the doped PEDOT: PSS film (Fig.…”

The paper presents the results of studies of the effect of tungsten disulfide nanoparticles on the optical and electrotransport characteristics of PEDOT: PSS thin films in polymer solar cells. Tungsten disulfide (WS2) nanoparticles were obtained by laser ablation in isopropyl alcohol. The average size of nanoparticles were determined by dynamic light scattering and is ~38 nm. The concentration of WS2 nanoparticles in the solution was calculated based on the density of the WS2 substance. The absorption spectrum of nanoparticles in isopropyl alcohol has been measured. Two bands are observed in 500-900 nm regions, which are associated with direct exciton transitions A1 and B1 in two-dimensional transition metal dichalcogenides with 2H phase. WS2 nanoparticles were added in PEDOT: PSS solution and thin films were deposited from the prepared solution by spin-coating. PEDOT: PSS thin films doped with WS2 were studied by atomic force microscopy (AFM). The arithmetic mean deviation of the surface roughness (Ra) was estimated. Doping with WS2 nanoparticles leads to the increase in Ra of PEDOT: PSS thin films. The optical absorption spectra of doped films have been measured. Also, doping PEDOT: PSS with WS2 nanoparticles results in a long-wavelength shift of the PEDOT absorption maximum. The optimal concentration of WS2 nanoparticles for the preparation of doped PEDOT: PSS thin films is determined, at which the film resistance decreases by almost 2 times, the recombination resistance of charge carriers increases by 4.7 times, and the efficiency of the polymer solar cell increases to 1.94 %.

“…Previous studies have reported to have observed the same effect in various alcoholic solvents, such as methanol, isopropyl alcohol, and 2-methoxy ethanol from the removal of excess PSS owing to the hydrophilicity of alcoholic solvents. 22–24 Conversely, the Seebeck coefficient decreases as the EtOH content increases, from 26.798 μV K −1 at 10 wt% EtOH to a minimum of 19.944 μV K −1 at 30 wt% EtOH. The decrease in Seebeck coefficient is due to the trade-off relationship with the electrical conductivity given by the Mott relationship.…”

“…Polystyrene sulfonate (PSS) on the PEDOT backbone resulted in a polymer (PEDOT:PSS) that is soluble in water and other organic solvents, facilitating its solution processability. Due to the high electrical conductivity, optical properties, and easy processing of PEDOT:PSS, its application in different flexible electronic devices such as light emitting diodes (LEDs), solar cells, and supercapacitors has been widely exploited. Also, the use of PEDOT:PSS as a coating, thin film, or active material has been widely reported .…”

The increasing demand for flexible electronic devices has risen due to the high interest in electronic textiles (e-textiles). Consequently, the urge to power e-textiles has sparked enormous interest in flexible energy storage devices. One-dimensional (1D) configuration supercapacitors are the most promising technology for textile applications, but often their production involves complex synthesis techniques and expensive materials. This work unveils the use of the novel electrospray deposition (ESD) technique for the deposition of poly(3,4-ethylenedioxythiophene)–poly(styrene sulfonate) (PEDOT:PSS). This deposition methodology on conductive carbon yarns creates flexible electrodes with a high surface area. The deposition conditions of PEDOT:PSS were optimized, and their influence on the electrochemical performance of a 1D symmetric supercapacitor with a cellulose-based gel as an electrolyte and a separator was evaluated. The tests herein reported show that these capacitors exhibited a high specific capacitance of 72 mF g–1, an excellent cyclability of more than 85% capacitance retention after 1500 cycles, and an outstanding capability of bending.
