Tungsten (IV) Selenide Powder Description
Tungsten (IV) Selenide Powder, with the chemical formula WSe2, is a unique inorganic compound. Its structure features selenium atoms forming upper and lower layers, with tungsten atoms sandwiched in between. Similar to graphene, WSe2 has the remarkable ability to absorb light, which can then be converted into electricity.
According to relevant reports, the Vienna University of Technology in Austria has developed the first diode made from tungsten diselenide (WSe2). Experiments have shown that this material can be used in ultra-thin flexible solar cells.
