General description

Antimony(III) selenide (Sb2Se3) is a ribboned non-toxic and low-cost material with a band gap of ~1.1 eV. Its properties include switching effects, good photovoltaic and thermoelectric properties. It can be prepared in the form of thin films by a number of methods such as vacuum evaporation, solution growth, spray pyrolysis and direct fusion of antimony and selenium.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

Sb2Se3 is a semiconducting material that can be used in a variety of applications such as lithium ion batteries, photovoltaic cells, solar cells, high performance field effect emitters, and photodetectors.(6)
