“…However, the mechanism of conductivity enhancement varies widely across the literature. [7,[34][35][36][37][38] Here, PEDOT:SPES film was immersed in DMF for secondary doping. The effect on conductivity due to the solvent treatment is listed in Table 1.…”

“…PEDOT has been extensively investigated for various device applications such as touch panels, organic light-emitting DOI: 10.1002/macp.202300143 diodes, organic photovoltaics, supercapacitors, antistatic coatings, sensors, and actuators. [1][2][3][4][5][6][7][8][9][10][11][12][13] In these device applications, PEDOT has been considered to replace indium tin oxide (ITO) due to various inherent drawbacks of ITO such as limited availability, high-temperature processing and cost, brittleness (unsuitable for a large area, and flexible and bendable applications), and high series resistance due to incompatibility with polymeric substrates. [11] PEDOT was first synthesized by Bayer AG Laboratories in the late 1980s and commercialized under the trade name Baytron.…”

Here the synthesis of poly(3,4‐ethylenedioxythiophene) (PEDOT) aqueous dispersion using sulfonated poly(ether sulfone) (SPES) with hydrophobic fluorinated groups to improve the weather and water stability of the conductive film is reported. The conductivity and surface morphology of the fabricated PEDOT:SPES conductive thin films are investigated. The PEDOT:SPES film after the N,N‐dimethylformamide (DMF) treatment showed a 200 times increase in the conductivity and the transmittance is over 96.5%. Raman spectroscopy indicates conformational changes in PEDOT chains due to the solvent treatment. The PEDOT:SPES film shows better water and weather stability performance in terms of dimensional stability in comparison to the commercial PEDOT:poly(styrene sulfonic acid) (PSS). Further, the organic solar cells performance is tested using PEDOT:SPES as hole transport layer and poly(3‐hexylthiophene) (P3HT):[6,6]‐phenyl C71‐butyric acid methyl ester (PC71BM) as active material. The PEDOT:SPES achieves a good power conversion efficiency (=3.36%), comparable with the conventional PEDOT:PSS (AI 4083).

“…This may be done by adding organic solvents such as dimethyl sulfoxide (DMSO) and ethylene glycol or poly(alcohols) such as glycerol and sorbitol. Sodium dodecyl sulfate, poly(oxyethylene) phenyl ether, and hexadecyltrimethylammonium bromide can also be used, as can sulfuric acid (H 2 SO 4 ), phosphoric acid (H 3 PO 4 ), and sulfonic acid. − Composites employ PEDOT:PSS, a conductive polymer. PEDOT:PSS possesses excellent film-forming properties, visual transparency, thermal stability, and secondary doping for tunable and enhanced conductivity.…”

In this study, we have established an efficient method to develop a solution-processed ultraviolet (UV) sensor with easy fabrication, a high response, and cost-effectiveness. Aiming at this, we developed a platform to utilize the synergistic effect of a hybrid network comprising a conducting polymer poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PE-DOT:PSS) and inorganic and organic UV sensitive materials, titanium dioxide (TiO 2 ) nanoparticles and carbon quantum dots (CQDs):TiO 2 nanocomposites, respectively. With the addition of the organic solvent dimethyl sulfoxide (DMSO) to the nanocomposites, the structural architecture of the hybrid film was altered, leading to the enhancement of the overall responsivity and conductivity of the sensor. The structural modifications in the hybrid film were confirmed through Raman spectroscopy, whereby peak shifts were detected. The hybrid film was fabricated on the silicon wafer (p-type) by using a simple drop-cast technique. Upon the illumination of UV radiation on the hybrid film, the change in conductivity was measured for light and dark modes. The proposed sensors demonstrated responsivity of 48.6% and response and recovery times of 235 and 360 s, respectively, for UV on/off cycles, which was substantially greater than that of the pristine PEDOT:PSS films, whose responsivity was 7.27% and response and recovery times of 753 and 856 s, respectively. The proposed sensor can be used in UV sensing applications for the detection of skin cancer, premature aging, and several other UV-induced skin ailments.
