CAS 12067-46-8 Tungsten diselenide Powder WSe2 used to make thin-film solar cells
Breif introduction of Tungsten diselenide Powder WSe2
Tungsten diselenide is an inorganic compound with the formula WSe2.
The compound adopts a hexagonal crystalline structure similar to molybdenum disulfide.
Every tungsten atom is covalently bonded to six selenium ligands in a trigonal prismatic coordination sphere while each selenium is bonded to three tungsten atoms in a pyramidal geometry.
The tungsten–selenium bond has a length of 0.2526 nm, and the distance between selenium atoms is 0.334 nm.
Layers stack together via van der Waals interactions.
WSe2 is a very stable semiconductor in the group-VI transition metal dichalcogenides.
Application of Tungsten diselenide Powder WSe2
Used to make transparent photovoltaic devices,thin-film solar cells
