“…For achieving higher efficiency, top-emitting architectures [182][183][184][185] and nanostructured/scattered electrodes or substrates [47,[130][131][132][133][134][135] can be adopted, to enhance output coupling or light extraction of the devices. However, to achieve high flexibility, extremely bendable TFC electrodes firstly need to be developed [88,120,124,146,147,177,186]. Yu et al [120] developed an AgNWs/shape-memory-polymer composite electrode deposited on PET substrate on which a flexible yellow OLED with minimum R b of 2.5 mm has been constructed.…”

“…In addition, these buckled PLEDs exhibit favorable stretchability and compressibility, which can tolerate 100% tensile strain and 50% compress, respectively. Nagata et al [88] developed a smooth, ultraflexible, and transparent electrode with AgNWs embedded in ultrathin (10 μm-thickness) cPI. This electrode film exhibits mechanical durability, for both outward and inward bending tests, up to a minimum R b of 30 μm, while maintaining its electrical performance after 100,000 bending cycles at R b = 500 μm.…”

Flexible thin-film organic semiconductor devices have received wide attention due to favorable properties such as light-weight, flexibility, reproducible semiconductor resources, easy tuning of functional properties via molecular tailoring, and low cost large-area solution-procession. Among them, ultraflexible electronics, usually with minimum bending radius of less than 1 mm, are essential for the development of epidermal and bio-implanted electronics, wearable electronics, collapsible and portable electronics, three dimensional (3D) surface compliable electronics, and bionics. This review firstly gives a brief introduction of development from flexible to ultraflexible organic semiconductor electronics, and design of ultraflexible devices, then summarizes the recent advances in ultraflexible thin-film organic semiconductor devices, focusing on organic field effect transistors, organic light-emitting diodes, organic solar cells and organic memory devices.

“…Among TCPs, Polyaniline (PANI), Polypyrrole (PPy), and PEDOT: PSS are well-known polymers [13][14][15][16], but PEDOT: PSS is most preferred materials because of its low sheet resistance and high transmittance [14,16]. The conductivity of PEDOT: PSS can be enhanced by chemical treatment with some solvent including sulfuric acid, formic acid, Polyethylene Glycol, N,N-dimethyl formamide, xylitol, tetrahydrofuran, methoxyethanol, and dimethyl sulfoxide (DMSO) [17][18][19][20][21][22][23][24][25][26], [27]. Despite this, PEDOT:PSS has several problems such as inhomogeneous electrical properties and poor long-term stability [28,29].…”

Present article reports on reduced graphene oxide (rGO) modified poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT: PSS) based transparent conducting electrodes for flexible optoelectronic applications. PEDOT: PSS samples embedded with different rGO concentrations i.e. 0, 1, 2, 3, 4, 5 wt% were prepared and later on, bar coated on polyethylene terephthalate substrate using a 30 μm wire size bar. Various parameters including sheet resistance, bending test (outside and inside bending), optical transmittance etc. were estimated. Our analysis indicates that the samples with 1 wt% rGO possess improved results i.e. low sheet resistance (315 ± 8 Ω/sq.) and high transmittance (~ 74%). Additionally, the sample shows low electrical resistance variation up to 12% (maximum increase) during outward bending and 9% (maximum decrease) during inward bending of the sample for bending curvature from 20 to 100 m−1.

Summary Silica (SiO2) and titania (TiO2) nanoparticles (NPs) have been separately known to aid in the enhancement of hybrid solar cell performance when embedded in the organic poly(3,4‐ethylene dioxythiophene) poly(styrene sulfonate) (PEDOT:PSS) layer. Individually, these materials only enhance the short circuit current density (JSC) or the open‐circuit voltage (VOC) of the device. In this research, we have introduced strategically designed nanocomposite (NC) of SiO2 and TiO2 NPs optimally embedded in the PEDOT:PSS hole transporting layer with a facile yet effective method to better enhance the JSC as well as the VOC and thus the overall performance of the hybrid solar cell by their synergistic effect. Various characterization techniques have been implemented to evaluate the synthesized materials as well as the fabricated device performance. The resultant optimal device with SiO2–‐TiO2 NC embedment provided an efficiency of 10.27% boosted from 8.21% for the reference device without the NC. The JSC, VOC, and fill factor values for the resultant device were boosted from 25.8 to 26.3 mA.cm−2, 0.56 to 0.58 V, and 56.8 to 67.5%, respectively. Our work demonstrates the elusive challenges to improve the efficiency of solar cells for new era technology.
