A ternary and composite MoIn2S4@CNTs counter electrode (CE) with a hedgehog ball structure was synthesized by using a facile one-step hydrothermal method. The composite MoIn2S4@CNTs film possesses large specific surface area through N2 adsorption-desorption isotherms test, which is advantageous to adsorb more electrolyte and provide larger active contact area for the electrode. In addition, the composite MoIn2S4@CNTs CE exhibits low charge transfer resistance and fine electrocatalytic ability made from a series of electrochemical tests including cyclic voltammetry, electrochemical impedance, and Tafel curves. Under optimal conditions, the DSSC based on the MoIn2S4@CNTs-2 composite CE achieves an impressive power conversion efficiency as high as 8.38%, which remarkably exceeds that of the DSSCs with the MoIn2S4 CE (7.44%) and the Pt electrode (8.01%). The current work provides a simplified preparation process for the DSSCs.

“…After 1.0 wt% Pt was loaded onto the Cf CE, the corresponding DSC exhibited a high PCE of 8.97%, which could match that of the Pt‐CE‐based DSC (9.41%). Moreover, a class of Cf‐based composite CEs were prepared for DSCs, including MoS 2 /Cf, VO 2 /Cf, Ni/Cf, MoO 2 /Cf, Pt 3 Ni/Cf, and Co 3 S 4 /Cf . All of the synthesized Cf‐based composite CEs showed higher catalytic activities than did the pristine Cf, and the catalytic improvements could be ascribed to the following possible reasons: 1) the high intrinsic catalytic activity of Cf, ) the synergistic catalytic effect of the loaded contents and the Cf support, ) the enhanced conductivity, ) the highly accessible surface area, and ) the constructed loose porous diffusion channels.…”

Developing highly effective and stable counter electrode (CE) materials to replace rare and expensive noble metals for dye‐sensitized and perovskite solar cells (DSC and PSC) is a research hotspot. Carbon materials are identified as the most qualified noble metal‐free CEs for the commercialization of the two photovoltaic devices due to their merits of low cost, excellent activity, and superior stability. Herein, carbonaceous CE materials are reviewed extensively with respect to the two devices. For DSC, a classified discussion according to the morphology is presented because electrode properties are closely related to the specific porosity or nanostructure of carbon materials. The pivotal factors influencing the catalytic behavior of carbon CEs are also discussed. For PSC, an overview of the new carbon CE materials is addressed comprehensively. Moreover, the modification techniques to improve the interfacial contact between the perovskite and carbon layers, aiming to enhance the photovoltaic performance, are also demonstrated. Finally, the development directions, main challenges, and coping approaches with respect to the carbon CE in DSC and PSC are stated.

Therefore, it is necessary to develop highperformance energy storage devices for facilitating the effective utilization of intermittent renewable energy sources. [7][8][9] Among varieties of electrochemical energy storage devices, supercapacitors (known as electrochemical capacitors) [10,11] and some rechargeable batteries (lithium-ion batteries (LIBs), lithiumsulfur (Li-S) batteries, and metal-O 2 batteries) [12][13][14][15] are at the frontier, because they can transport high power and store high energy. Nowadays, they play an indispensable role in our daily life by powering numerous portable electronic devices (e.g., cell phones and laptops), hybrid electric vehicles, and large-scale electrical grids. [16][17][18][19] It is well accepted that the performance of energy storage devices mainly depended on their electrode materials. [20,21] Owing to the advantages of large surface area, light weight, good electrical conductivity, and high thermal/ chemical stability, carbon materials have been considered as the most important electrode materials of supercapacitors and rechargeable batteries [8,20,21] Hence, various nanostructured carbons, such as carbon/graphene quantum dots, [22,23] carbon nanofiber (CNFs), [16,24] carbon nanotubes (CNTs), [13,25] graphene [26][27][28][29][30][31][32] carbon nanosheets, [33,34] 3D carbon nanostructures, [35][36][37] and porous carbon, [38,39] have gained great attention. Among these materials, 3D carbon nanomaterials have some advantages. The interlinked architecture not only shortens transport distances for ions in the well-interconnected wall structure, but also provides a continuous pathway endowing for the fast electron transport. [40] Moreover, the structural interconnectivities guarantee higher electrical conductivity and better mechanical stability. [36,41] Thereby, the design and fabrication of various 3D carbonbased nanostructures, including carbon nanotube networks, graphene gels, graphene foams, and 3D CNFs, have been intensively investigated.Over the past few years, there are many reviews summarizing the progress of fabricating 3D carbon-based nanomaterials. For example, Schneider et al. overviewed the recent advance in the synthesis of 3D arranged carbon nanotube architectures. [42] Li et al. reviewed the carbon-based 3D nanostructures for supercapacitors. [36] Cao and Gui et al. comprehensively reviewed the recent progress in synthesis, properties, and energy applications of CNT sponges, aerogels, and hierarchical composites. [43] The development of high-performance electrochemical energy storage devices is critical for addressing energy crises and environmental pollution.
