Electrochemical solar cells with layer-type semiconductor anodes. Performance of n-MoSe2 cells

Review of material properties of (Mo/W)Se2-layered compound semiconductors useful for photoelectrochemical solar cells

“…The indirect band gap value of 1.23 eV and lattice parameters a ¼ b ¼ 3.288 and c ¼ 12.90 Å were reported. The difference between the shapes reflects the difference of the components of the wave functions (47). The nMoSe 2 crystals were grown by a direct vapour transport technique and characterized using electron dispersive analysis by X-rays (EDAX).…”

σ-Aromaticity in the MoS2 Monolayer

“…The configuration of stacked layers exhibits properties of a dry lubricant, which found an application in aerospace technologies. , Besides its outstanding mechanical characteristics, this layered material has the ability to transform from an indirect band gap of 1.2 eV in bulk to a direct band gap of 1.9 eV in the monolayer. , Due to its unique electronic − and optical , properties including tunable band gap, ,, MoS 2 is one of the most intensively studied materials in the world. Different crystal phases , of this TMD compound have a great variety of potential applications in solar batteries, − sensors, and detectors − due to the high band-edge excitation of d–d transitions. Despite the continuously growing number of publications dedicated to MoS 2 , some of its fundamental aspects still remain unclear.…”

Photosensitization of Nanostructured TiO2 with WS2 Quantum Sheets

“…However, it is well-known that step sites and surfaces perpendicular to the c -axis pose major problems as recombination centers for photogenerated charges. Many efforts have therefore been undertaken to chemically passivate such surface sites by chemical modification or attachment of molecular species. − A nanosolar cell based on WS 2 will therefore necessarily include efforts toward chemical passivation of such undesirable properties on the nanoscale.…”
