“…In addition, the difference of binding energy between Mo 3d 5/2 and Co 2p 3/2 (~550.00 eV) is a useful standard to judge whether the CoMoS phase formed. [31][32][33] For the obtained CoP/ CoMoS/CC, this value is 550.29 eV, further confirming the existence of Co 0.75 Mo 3 S 3.75 phase. In Figure 3c, the two distinct peaks at 161.91 and 163.38 eV are attributed to S 2À and the other two peaks at 163.52 and 164.84 eV belong to apical S 2À or bridging S 2 2À .…”

Currently, the construction of heterostructures to optimize electrocatalytic activities is a hot research topic, since there is still a certain gap between the electrocatalytic properties of these heterostructures and that of Pt/C. With this in mind, we utilized in‐situ vapor‐phase phosphorization‐sulfurization to obtain the CoP3/MoS2−Co0.75Mo3S3.75 (CoP/CoMoS, for short) heterostructure on carbon cloth (CC), which exhibits Pt‐like electrocatalytic performance and excellent stability in acid electrolyte. Activated by CoP3 active phase, the electronic configuration of CoMoS and the adsorption energy of H* (▵GH*) are greatly optimized. Meanwhile, the rapid oxidation of CoMoS phase can be effectively avoided under the protection of CoP3 layer. This work provides a reference for the design of heterostructures and their mechanism of action in electrocatalysis.

“…The abundant catalytic active sites, superior carrier transfer properties of graphene, and low resistance of MoS 2 @RGO lead to a good PCE of 6.82%, which is better than that of Pt counter electrode DSSCs (6.44%). GP was also a great candidate as substrate, as reported by Zheng et al 166 The MoS 2 /GP counter electrode has shown a smaller series resistance for I 3 − reduction in compare with that of Pt/FTO counter electrode. In order to increase the photoelectric conversion efficiency and improve the electrical conductivity of the counter electrode, the Co doping process has also been employed.…”

Being confronted with the energy crisis and environmental problems, the exploration of clean and renewable energy materials as well as their devices are urgently demanded. Dye‐sensitized solar cells (DSSCs) have attracted widespread attention in recent years as potential cost‐effective alternatives to silicon‐based and thin film solar cells. Two‐dimensional (2D) graphene‐like transition metal dichalcogenides (TMDs), such as WS2 and MoS2, have showed vast potential as novel energy materials due to their unique physicochemical properties. In this review, we outline the applications of WS2 and MoS2 as counter electrode materials in DSSCs. First, a brief introduction of structures and basic properties of WS2 and MoS2 are presented. Then, we summarize the exciting progress of these two materials for DSSCs. Finally, the prospect and further developments in these exciting fields of TMDs are also suggested.

The photoelectric conversion efficiency (PCE) of dye‐sensitized solar cells (DSSCs) can be remarkably improved by optimizing the catalytic activity and charge transfer ability of the counter electrode (CE) materials. The attentive hotspots of CE catalysts for DSSCs are to design multifunctional materials that balance the fabrication cost, environmental friendliness, PCE, and electrochemical stability, then to achieve the substitution of the benchmark Pt. In this review, the four effective strategies are highlighted for further improving the photovoltaic performance of the DSSCs based on low‐cost CE materials, such as heteroatom‐doped materials, development of noble metal‐free chalcogenides with well‐controlled facets, construction of heterostructure, and synthesis of composites with a synergistic effect. In some typical examples, the influence of these strategies on catalytic activity, charge transfer ability, and reaction mechanism are elucidated by the theoretical calculation. Then the research opportunities and the challenges for the high‐efficiency DSSCs based on low‐cost CE materials are presented.
