“…Despite these significant progresses, the electrical performances of FETs based on the conductive 2D-COFs cannot match those made from traditional organic conductive polymers, such as poly(3-hexylthiophene), copper Pc, TTF, tetracyanoquinodimethane, and so on. [133][134][135][136][137][138][139][140][141][142] Although singlelayer 2D-COFs are theoretically predicted to offer a charge carrier mobility up to 95 cm 2 V −1 s −1 , [143] the experimental studies often rely on the crystalline 2D networks with micropowder or multi-layer morphologies. [18,92,118] In spite of the fact that some few-layer conductive 2D-COFs have charge carrier mobilities measured up to 20.6 cm 2 V −1 s −1 , [57,93,94] great efforts are required to improve the performance of COFs based FETs for large-scale electronics.…”

“…Poly (3-hexylthiophene) was chosen as the organic semiconductor for the second part of device components because it h has been widely used in polymer-based electronics such as transistors and solar cells (Yang et al, 2017). The P3HT solution for spin coating was prepared by weighing regioregular poly (3-hexylthiophene-2,5-diyl) (0.1g, Sigma-Aldrich) into a 5 mL volumetric flask, and then topping up with chloroform (Aldrich Chemical, UK).…”

The influence of the morphology and thickness of titanium dioxide (TiO2) films in solar cells based on dioxide materials-semiconducting polymer was investigated. These parameters can significantly impact the mechanism of charge generation in double-layer solar cells. TiO2 films were deposited on glass surfaces using two different techniques. Atomic force microscopy examination revealed a crystalline structure in the thick TiO2 film produced using the doctor blade technique, whereas an amorphous structure and thin layer were obtained via the spin-coating technique. Under light conditions, the best performance between the two solar cells was obtained with the amorphous TiO2thin film, which displayed a higher short circuit current density and power conversion efficiency (Jsc=1mA/cm 2 , μ=0.24%) than the nanocrystallineTiO2 solar cell (Jsc=0. 23mA/cm 2 , μ=0.1%). This is explained by the improved efficiencies of hole-electron pair separation and charge collection through reductions in the resistance across the bulk region and in charge recombination at the interfacial layer in the amorphous solar cell. However, the high rectification ratio and high turn-on voltage under dark conditions, and forward bias current in the nanocrystalline solar cell led to an increase of 0.3 V in the open circuit voltage in comparison with the amorphous device. These results confirm that, for double-layer solar cells, an amorphous thin film performs better than a thick nanocrystalline TiO₂ layer, in contrast to previous observations for dye-sensitized solar cells.

“…In comparison with the above mentioned conductive materials, the advantage of the conductive polymers is their processability, especially through the solution process. Conductive polymers have been widely investigated in various applications, such as solar cells [ 7 ], transistor [ 8 ], thermoelectric power-generation [ 9 ], microwave absorption [ 10 ], electrochromic devices [ 11 ], photocurrent generation [ 12 ], supercapacitors [ 13 ], and light emitting diodes [ 14 , 15 , 16 ]. The composite photocatalysts can be prepared by incorporating conductive polymers (especially polyaniline, polypyrrole, PEDOT, and polythiophene) with semiconductor nanomaterials.…”

Conductive polymers have been widely investigated in various applications. Several conductive polymers, such as polyaniline (PANI), polypyrrole (PPy), poly(3,4-ethylenedioxythiophene) (PEDOT)), and polythiophene (PTh) have been loaded with various semiconductor nanomaterials to prepare the composite photocatalysts. However, a critical review of conductive polymer-based composite photocatalysts has not been available yet. Therefore, in this review, we summarized the applications of conductive polymers in the preparation of composite photocatalysts for photocatalytic degradation of hazardous chemicals, antibacterial, and photocatalytic hydrogen production. Various materials were systematically surveyed to illustrate their preparation methods, morphologies, and photocatalytic performances. The synergic effect between conductive polymers and semiconductor nanomaterials were observed for a lot of composite photocatalysts. The band structures of the composite photocatalysts can be analyzed to explain the mechanism of their enhanced photocatalytic activity. The incorporation of conductive polymers can result in significantly improved visible-light driven photocatalytic activity by enhancing the separation of photoexcited charge carriers, extending the light absorption range, increasing the adsorption of reactants, inhibiting photo-corrosion, and reducing the formation of large aggregates. This review provides a systematic concept about how conductive polymers can improve the performance of composite photocatalysts.
