Study of the effect of DMSO concentration on the thickness of the PSS insulating barrier in PEDOT:PSS thin films

Effective Approaches to Improve the Electrical Conductivity of PEDOT:PSS: A Review

“…[ 80 ] The hydrophilic nature of PSS and the hydrophobic nature of PEDOT offer a means for selective de-doping of PSS through the use of hydrophilic solvents such as EG. Kim et al prepared PEDOT:PSS fi lms by adding DMSO (or EG) into the PEDOT:PSS (Clevios PH 1000) aqueous solution and subsequent treatment [32] 7 × 10 −2 73 Cruz-Cruz et al [33] 10 −2 130 Wilson et al [34] 0.8 ± 0.1 80 ± 30 Kim et al [8] 0.2 (Clevios PH 510) 300 Wang et al [35] 0.2 (Clevios PH 500) 526 Na et al [36] <1 (Clevios PH 500) 550 Na et al [37] 0.2-1(Clevios T PH1000) 600 Hokazono et al [38] 0.2 (Clevios PH 1000) 670. 5 Lim et al [39] 0.2-1 (Clevios P) 677 Lee et al [40] 9 (Clevios P) 48 Jiang et al [41] 39 (Clevios P) 298 Liu et al [42] EG 2.2 × 10 −2 1.3 Dimitriev et al [32] 0.4 (Clevios P) 160 Ouyang et al [43] 0.4 200 Ouyang et al [19] 0.4 (Clevios PH 500) 443 Yan et al [44] 9 55 Jiang et al [41] 39 242 Liu et al [42] 15.64 274.…”

Metal salt modified PEDOT:PSS as anode buffer layer and its effect on power conversion efficiency of organic solar cells

“…Poly (3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate), abbreviated as PEDOT:PSS has been widely known as one of the most promising conductive polymers employed as a hole transporting layer, due to its simple processing, high transparency and high stability. It is considered as a favorable material to replace inorganic materials to deposit on flexible substrates for plastic electronics applications such as memories, sensors, OLEDs and flexible PV devices [5]. PEDOT:PSS dispersed in water can easily form a transparent film with high conductivity by spin coating, thus producing a low sheet resistance film [6].…”

Development of bifacial inverted polymer solar cells using a conductivity-controlled transparent PEDOT:PSS and a striped Au electrode on the hole collection side

“…Clevios P+ represents the Clevios P film after being processed with 2-propanol 27) . It is known that conductivity of PEDOT:PSS enhances by treatment with sugar alcohol 28,29) , organic solvent [30][31][32] and surfactant. However, when Clevios PHCV4 with the lowest sheet resistance was 6 used as the hole collection layer, the short circuit photocurrent (J sc ), the open light voltage (V oc ) and fill factor (FF) were lower than those of the other devices, and resulted in the P w being quite low.…”
