“…Both the TMDC materials show higher stability and resistance towards photocorrosion as compared to other organic solar cells 218 . Many of the recent reports have shown that transition metal dichalcogenides and their hybrids can be synthesized in a very cost effective way and have the ability to actively absorb much more radiated energy from the solar energy spectra as compared to the conventional solar cells made from both organic materials as well as silicon [219][220][221] . Furthermore, the relative thickness of the fabricated devices using TMDCs would be much less, bringing in the possibility for transparent, light weight and flexible solar cells.…”

Atomically thin semiconducting transition metal dichalcogenides (TMDCs) layered materials have recently been emerged as an exciting area of research due to accessibility for easy synthesis using various chemical and physical methods. These two-dimensional (2D) layered materials with single layer have direct and wide band gap due to which, they are more suitable for nanoelectronics and optoelectronics device applications. Here, we present a review of the energy related aspects of atomically thin layered materials like MoS 2 , WS 2 , MoSe 2 , WSe 2 , InSe, GaSe, GaTe, MoTe 2 , WTe 2 etc. for supercapacitor, solar cell, lithium ion battery and water splitting application. By significantly assessing various materials and comparing their performances with challenging technology, the advantages and disadvantages of this promising area of energy materials are recognized, which may provide guidelines for future progress.

“…J 0 represents the slope of the Tafel curve and is inversely proportional to R ct (Equation 7). 87 J O = R · T n · F · R ct [7] R is the Avogadro constant, n is the number of electrons transferred in the redox reaction, and F is the Faraday constant. However, platinum is one of the scarcest elements constituting a major bottleneck for the introduction of DSSCs into the market.…”

Efforts in the broad field of dye-sensitized solar cells (DSSC) are governed by four key challenges: i) the development of photoelectrodes with high charge injection yields and charge collection efficiencies, ii) the development of low-cost buffer layers, which effectively reduce the back reaction of electrons from the transparent conductive oxide (TCO) to the electrolyte, iii) the design of platinum-free counter electrodes (CE), which feature good electrolyte regeneration yields, and iv) the implementation of (quasi) solid-state and iodine-free electrolytes featuring excellent ionic diffusion and conductivity.

“…Therefore, coupling of MoS2 with other conductors to form composites is an efficient approach to expand the usage of MoS2 as catalyst in the field of electrochemistry. In previous reports, MoS2-based composites, such as, MoS2/graphene [21], MoS2/multi-walled carbon nanotube [22], and MoS2/carbon [23], led to significantly improved DSSCs performance, compared to pure MoS2 catalyst.…”

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.
