“…The electrochemical rate constant of the triiodide reduction is supposed to negatively correlated with the separation between the cathodic and anodic peak potential (ΔEpp) [14,15,33,34]. Mo/Co-14 CE has a ΔEpp of 0.50 V, slightly larger than that of Pt electrode, 0.35 V. This agrees well with the photovoltaic performance exhibited by the DSSCs based on Pt and composite CEs.…”

MoS2/Co3S4 composite films were prepared via a facile one-step hydrothermal method, and used as efficient and low-cost Pt-free counter electrodes (CEs) for dye-sensitized solar cells (DSSCs). Characterizations revealed that Co3S4 and MoS2 were obtained simultaneously during the facile hydrothermal process. The composites afforded a promising synergistic effect on the catalyzing of triiodide reduction. Enhanced electrocatalytic performance of the resultant composite films was confirmed through cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) analyses. DSSCs using MoS2/Co3S4 composite CEs outperform the devices with pristine MoS2 or Co3S4 CEs in power conversion efficiency (PCE). Furthermore, a PCE of 6.77% is obtained for the optimized devices using MoS2/Co3S4 composite CEs measured under standard 1 sun illumination (100 mW cm −2 , AM 1.5G), which is comparable to that of the devices fabricated under the same conditions with conventional thermally deposited Pt CEs (7.14%). The results demonstrate that MoS2/Co3S4 composites are promising alternatives to Pt to be applied as CEs for DSSCs.

The existing fiber-shaped energy storage devices include the supercapacitor, [15] the lithium (Li)-ion battery, [16] the lithium-sulfur battery, [17] the lithium-air battery, [18] the zinc-air battery, [19] the aluminum-air battery, [20] the sodiumion battery, [21] the zinc-ion battery, [22] and the silver-zinc battery. [23] Among them, the supercapacitor has been reported mostly due to the easy fabrication, and lithium-ion battery has laid the foundation for the development of other fiber-shaped batteries, which are thus discussed mainly in this review. 3) Light-emitting devices have been developed for various applications such as display, illumination, and photo therapy. According to the working mechanisms, there are electroluminescence, [24] mechanoluminescence, [25] photoluminescence, [26] thermoluminescence, [27] sonoluminescence, [28] and chemiluminescence. [29] Among these, fiber-shaped electroluminescent devices have been developed extensively due to their good controllability, driven by direct current (DC) [30] or alternating current (AC) [31] electrical method, which are expounded mainly later. 4) Fibershaped sensors have found great potentials in the field of wearable medical devices for fitness monitoring and medical diagnostics especially as aging populations grow. By virtue of the 1D structure, fiber-shaped sensors can be implanted into the body with little injure or they can detect multiple signals simultaneously after integration into a tiny unit. [32] Fiber-shaped sensors generally work via physical processes on the basis of conducting fiber [33] and optical fiber, [34] and chemical processes based on chemical ligand. [35] Thereinto, fiber optic sensors have already been used in petrochemical, electric power, medical, civil engineering, etc. The detailed discussions about the above three fiber-shaped sensors are presented in the later section.Despite the great progress made in fiber and textile electronics, we have to realize that most of the research results are far from practical applications due to several existing obstacles. The performances of fiber-shaped electronic devices are not good enough to attract investors. For instance, although fiber-shaped solar cells have achieved a record power conversion efficiency (PCE) of 10%, [36] this value falls far below the certified efficiency of 24.2% for planar solar cells. [37] Besides, fiber-shaped electronic devices often decay in performance further as their lengths increase. Apart from low performances, scalable fabrication is another hard nut to crack if fiber-shaped electronic devices are to be commercialized. For one thing, researchers usually can only realize fiber-shaped electronic devices with the lengths from several to hundreds of millimeters at present owing to the absence of appropr...

Fibers and textiles are attractive substrates for constructing wearables, the devices rely on conductive fibers with good stretchability to realize electrical conductivity and mechanical adaptivity. The exploitation of stretchable composite conductive fibers (SCCFs) requires diverse strategies in material options and process methods, tackling the challenge in balancing electrical and mechanical properties for ultrafine fiber, which highly determine the properties and applications. In this article, first the working mechanism and advantages of the SCCFs in wearables is introduced. Second, different conductive fillers as well as their respective incorporation strategies and performance superiorities in fabricating SCCFs are systematically summarized. Third, the integration routes of the conductive fillers in SCCFs are indicated and compared, presenting different fabrication strategies and mechanisms for improving the performance of SCCFs. Thereafter, the typical applications of SCCFs in energy management, sensing, actuators, heaters, and displays are highlighted.
