“…The pertinent photovoltaic parameters are listed in Table 1. The power conversion efficiency (η) of the DSSC with a composite film having equal weights of MoSe2 and PEDOT:PSS (MP-1.00) is 7.58 ± 0.05%, which is competitive with the efficiency of a Pt CE (7.81 ± 0.03%) [46]. Wang and his group predicted the trends in HER activity of MoS 2 structures with different transition metals (Co, Fe, Ni, Cu) doping via a computational descriptor-based approach [45].…”

“…Huang et al reported that a composite film of molybdenum diselenide nanosheets (MoSe 2 NSs)/poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) was fabricated using a low-cost drop-coating method for the counter electrode (CE) of a dyesensitized solar cell (DSSC) [46]. The morphological features of various CEs are shown in Figure 11.…”

Two-dimensional-layered transition metal dichalcogenides (2D-layered TMDs) are a chemically diverse class of compounds having variable band gaps and remarkable electrochemical properties, which make them potential materials for applications in the field of electrochemical energy. To date, 2D-layered TMDs have been wildly used in water-splitting systems, dye-sensitized solar cells, supercapacitors, and some catalysis systems, etc., and the pertinent devices exhibit good performances. However, several reports have also indicated that the active sites for catalytic reaction are mainly located on the edge sites of 2D-layered TMDs, and their basal plane shows poor activity toward catalysis reaction. Accordingly, many studies have reported various approaches, namely active-site engineering, to address this issue, including plasma treatment, edge site formation, heteroatom-doping, nano-sized TMD pieces, highly curved structures, and surface modification via nano-sized catalyst decoration, etc. In this article, we provide a short review for the active-site engineering on 2D-layered TMDs and their applications in electrochemical energy. Finally, the future perspectives for 2D-layered TMD catalysts will also be briefly discussed.

“…This method typically involves dispersion of CPs and MCs nanosheets separately in solvent using stirring or ultrasonication followed by mixing and filtration. For example, the counter electrode for dye-sensitized solar cells was prepared by depositing the composite of PEDOT: PSS/MoSe 2 by drop coating on different substrates [132]. PEDOT:PSS/MoSe 2 composite could replace Pt owing to its low-cost and good catalytic ability, that offers an opportunity for fabrication of flexible Pt-free dye-sensitized solar cells.…”
