Scalable Large-Area 2D-MoS2/Silicon-Nanowire Heterostructures for Enhancing Energy Storage Applications

“…The unique chalcogen–metal–chalcogen structure of transitional-metal dichalcogenides (TMDs) gives them unique properties such as the ability to retain large numbers of ions due to their interlayer spacing , (2H-MoS 2 6.5 Å, 1T-MoS 2 > 10 Å, tunable through addition of elements , ) and their intralayer stackable nature. TMDs can facilitate increased ionic interaction and increase electrical conduction within electrode/electrolyte interfaces in ionic batteries, leading to high-capacity batteries. ,, The ability to provide high capacity coupled with the high stability of these materials constitutes them as ideal candidates for battery electrodes and interfacial layers. − Other TMD properties including high mobility, tunable bandgap, high mechanical flexibility, high surface-to-volume ratio, and supercapacitive and catalytic activity offer unique property combinations for next-generation fuel cells , and solar cells. , Specifically, TMDs can act as power conversion efficiency enhancing layers in solar cells, , additionally increasing lifetime and dramatically reducing waste arising from solar panel replacement. TMDs can also be used in the cost-effective production of hydrogen, ,, resolving one of the most persistent stumbling blocks for its use as a clean energy source.…”
