Summary: Complex 3D geometry and high conductivity have been mutually exclusive characteristics for conducting polymers. However, this study reveals that the reduced conductivity in 3D-printed forms of PEDOT:PSS can be overcome by addressing the ink formulation strategy and lateral phase separation. By optimizing these factors, a significant enhancement in conductivity to 1200 S/cm, higher than the typical 2D-processed PEDOT:PSS, has been achieved.

Summary: In this study, a double heterojunction UV photodetection device was proposed and demonstrated, consisting of an ITO conductive glass, a p-type PEDOT:PSS polymer film, a single p-type ZnO:Sb MW, and an n-type Si substrate. The treated photodetector exhibited a strong photoresponsivity and high EQE, significantly higher than the pristine devices. The proposed double heterojunction meets the criteria of low cost and eco-friendly, making it a competitive option for large-scale fabrication of high-performance UV photodetectors.

Summary: In this study, WS2 nanosheets were doped into PEDOT:PSS as an efficient hole transport layer for organic solar cells, leading to improved performance. The PEDOT:PSS:WS2 NS anode interlayer showed higher work function, reduced roughness, and improved hole mobility, resulting in enhanced hole extraction and transportation, as well as improved fill factor and short-circuit current density in the devices. The power conversion efficiency (PCE) increased from 14.35% to 15.67% with WS2 NS doping based on PM6:Y6.

Summary: This research investigates the thermoelectric properties of Tellurium (Te) and Poly(3,4ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) hybrid composite thin film as well as double-layer structured of PEDOT/Te thin film. The results show that the PEDOT:PSS/Te double-layer structure offers improved conductivity and Seebeck coefficient compared to the hybrid structure, due to the formation of an ohmic contact interface between PEDOT:PSS and Te. The study provides experimental and theoretical support for the development of thin-film thermoelectric materials and devices.

Summary: A method of introducing a PEDOT:PSS layer on a zinc anode to tackle the dendrite issue is presented. The well-ordered PEDOT:PSS layer can effectively regulate the deposition direction of zinc ions, preventing dendrite growth. Symmetrical cells assembled with PEDOT:PSS@Zn demonstrate dendrite-free zinc plating/stripping behavior, with stable cycling for extended periods of time.
