“…In contrast, the fibrous DSSCs with pristine CF or CF@TiO 2 counter electrodes only display V OC of 0.74 or 0.75 V, J SC of 16.05 or 16.10 mA cm −2 , FF of 0.51 or 0.54, η of 6.0% or 6.5%, respectively. It should be noted that, to the best of our knowledge, the η of 9.5% achieved by the CF@TiO 2 @MoS 2 based fibrous DSSCs is the highest if comparing with other fibrous DSSCs in previous reports (Table S1, Supporting Information) . The dramatic increased FF and η of CF@TiO 2 @MoS 2 based fibrous DSSCs is ascribed to the high electrocatalytic activity of MoS 2 and the rapid charge‐transfer kinetic process occurring on the electrolyte‐counter electrode interface.…”

Here an all-purpose fibrous electrode based on MoS 2 is demonstrated, which can be employed for versatile energy harvesting and storage applications. In this coaxial electrode, ultrathin MoS 2 nanofilms are grown on TiO 2 nanoparticles coated carbon fiber. The high electrochemical activity of MoS 2 and good conductivity of carbon fiber synergistically lead to the remarkable performances of this novel composite electrode in fibrous dye-sensitized solar cells (showing a record-breaking conversion efficiency of 9.5%) and high-capacity fibrous supercapacitors. Furthermore, a self-powering energy fiber is fabricated by combining a fibrous dye-sensitized solar cell and a fibrous supercapacitor into a single device, showing very fast charging capability (charging in 7 s under AM1.5G solar illumination) and an overall photochemical-electricity energy conversion efficiency as high as 1.8%. In addition, this wire-shaped electrode can also be used for fibrous Li-ion batteries and electrocatalytic hydrogen evolution reactions. These applications indicate that the MoS 2based all-purpose fibrous electrode has great potential for the construction of high-performance flexible and wearable energy devices.

“…There are other reported QD fabrication and conversion methods 21 with differences in growth times and temperatures; however, a key difference is that our QDs have a core-shell structure that avoids possible leakage of heavy metal in the QD cores. This may contribute signicantly to the fact that free 3MPA-QDs showed no toxicity to Calu-3 cells.…”

“…Apart from CF, CNTs were also utilized as fiber‐shaped substrates. Yan et al demonstrated an all‐carbon based FDSCs by using TiO 2 NPs coated carbon nanotube yarns (CNYs) wire as photoanode, a single CNY wire twisting on the photoanode as CE . CdS and CdSe quantum dots and N719 dye cosensitized the TiO 2 NPs.…”

The rapid development of the modern electronics gives rise to higher demands of flexible and wearable energy resources. Flexible transparent conducting electrodes (TCEs) are one of the essential components for flexible/wearable thin-film solar cells (SCs). In this regard, commercial indium tin oxide (ITO) on plastics has demonstrated superior optoelectronic performance although some drawbacks, i.e., the low abundance, film brittleness, low infrared transmittance, and poor chemical stability remain. On the other hand, several other transparent conducting oxide (TCO)-free transparent conductive materials, such as carbon nanotubes (CNTs), graphene, metallic nanowires (NWs), and conducting polymers, have experienced a rapid development to address these issues. In this feature article, an overview over the latest development of several flexible TCO-free thin film SCs, i.e., organic solar cells (OSCs), dye-sensitized solar cells (DSSCs), perovskite solar cells (pero-SCs), and fiber/wire-shaped SCs is provided. Three groups of flexible TCO-free thin film solar cells can be categorized according to their configurations: (i) frontside illuminated planar configuration; (ii) back-side illuminated planar configuration, and (iii) fiber-shaped solar cells (FSSCs). The article is focused onflexible TCO-free TCEs, including CNTs, graphene, metallic NW/nanotroughs, metallic grids, conducting polymers, metallic fiber, and carbon based fibers. applications in energy conversion and storage. [8] However, more coverage and concept have been raised and some new type SCs have been developed these years.To systematically summarize different TCO-free TCFs and their applications in thin film SCs, here we attempt to categorize flexible ITO-free thin film SCs into three groups according to their configurations (Figure 1): (i) light is supposed to irradiate from flat photoanodes/TCFs side (front-side illuminated configuration); (ii) photoanode on an opaque substrate and light is supposed to irradiate from a transparent top electrode (back-side illuminated configuration); and (iii) both active layers and counter electrodes (CEs) are fabricated onto cylindrical substrates (flexible fiber-shaped solar cells (FSSCs)). In this review, the latest progress on flexible TCO-free thin film SCs including OSCs, DSSCs, QDSCs, pero-SCs, and fiber/ wire-shaped SCs are presented. Focus was given to their flexible TCO-free TCFs including CNTs, graphene, metallic NW/ nanotroughs, metallic grids, conducting polymers, metallic fiber, and carbon based fibers. The aim of this feature article is to give an overview on the various recent works on flexible ITO-free thin film SCs done by researchers to develop new-style TCEs. The paper will be arranged according to three different configurations as shown in Figure 1. Front-Side Illuminated TCO-Free Flexible Thin Film SCsThese years, most research efforts have been put into designing and fabricating TCO-free flexible thin film SCs with frontside illuminated configuration. A key issue in the fabrication of such SC is s...
