“…Electronic energy band gap of P3HT is ~1.9 eV, with the majority of absorbed light from the visible part of the solar spectrum [ 15 , 16 ]. The bulk heterojunction layer was prepared on top of the hole-transport layer of poly(3,4-ethylenedioxythiophene) polymer, crosslinked with the poly(styrenesulfonic acid) (PEDOT:PSS) [ 17 ]. PEDOT:PSS layer is characterized by high hole conductivity, optically transparent and forms suitable interface dipole with P3HT:PCBM for photogenerated charge extraction [ 14 ].…”

The influence of P3HT:PCBM ratio on thermal and transport properties of solar cells were determined by photothermal beam deflection spectrometry, which is advantageous tool for non-destructively study of bulk heterojunction layers of organic solar cells. P3HT:PCBM layers of different P3HT:PCBM ratios were deposited on top of PEDOT:PSS/ITO layers which were included in organic bulk-heterojunction solar cells. The thermal diffusivity, energy gap and charge carrier lifetime were measured at different illumination conditions and with a different P3HT:PCBM ratios. As expected, it was found that the energy band gap depends on the P3HT:PCBM ratio. Thermal diffusivity is decreasing, while charge carrier lifetime is increasing with PCBM concentration. Energy band gap was found to be independent on illumination intensity, while thermal diffusivity was increasing and carrier lifetime was decreasing with illumination intensity. The carrier lifetime exhibits qualitatively similar dependence on the PCBM concentration when compared to the open-circuit voltage of operating solar cells under AM1.5 illumination. BDS and standard I-V measurement yielded comparable results arguing that the former is suitable for characterization of organic solar cells.

Benefiting from the advantages of high conductivity and good electrochemical stability, the conjugated conducting polymer poly (3, 4‐ethylenedioxythiophene) is a promising energy storage material in zinc‐ion batteries. Zinc‐ion batteries have the advantages of high safety, environmental friendliness, and low cost, but suffer from unstable cathode material structure, poor electrical conductivity, and uncontrollable dendritic growth of zinc anodes. PEDOT, with its fast electrochemical response and wide potential window, is expected to make up for the shortcomings and enhance capacity and cycle life of zinc‐ion batteries. Herein, in this review different polymerization methods of poly (3, 4‐ethylenedioxythiophene) as well as their structure and properties are summarized; the progress in doping strategies related to the increasing conductivity and dispersivity of poly (3, 4‐ethylenedioxythiophene) materials is discussed; specific applications of poly (3, 4‐ethylenedioxythiophene)‐based materials in anode, cathode, electrolyte, and binder of zinc‐ion batteries are explored; and the representative advancements for improving the electrochemical performance of poly (3, 4‐ethylenedioxythiophene) in zinc‐ion batteries are emphasized. Finally, the current challenges of poly (3, 4‐ethylenedioxythiophene) as promising materials in zinc‐ion batteries and an insight into their future research directions are pointed out.

Poly(3,4‐ethylenedioxythiophene) (PEDOT), particularly in its complex form with poly(styrene sulfonate) (PEDOT:PSS), stands out as a prominent example of an organic conductor. Renowned for its exceptional conductivity, substantial light transmissibility, water processability, and remarkable flexibility, PEDOT:PSS has earned its reputation as a leading conductive polymer. This study explores the unique effects of two additives, Bisphenol A diglycidyl ether (DGEBA) and Dimethyl sulfoxide (DMSO), on the PSS component of PEDOT:PSS films are shown. Both additives induce grain size growth, while DGEBA makes the PEDOT:PSS layer hydrophobic, which acts as a passivation to protect the perovskite layer, which is vulnerable to moisture. The other additive, DMSO, separates the PSS groups, resulting in increased conductivity through the free movement of holes. With these multi‐modified p‐type PEDOT:PSS, the ITO/M‐PEDOT:PSS/Perovskite/PCBM/Ag structured reverse structure solar cell has improved the power conversion efficiency (PCE) from 15.28% to 17.80% compared to the control cell with conventional PEDOT:PSS. It also maintains 90% for 500 h at 60 °C and 300 h at 1 sun illuminating conditions.
