Fluorine Doped Tin Oxide Powder Description
SnO2 has been proved a wide band-gap semiconductor that exhibits n-type character and high optical transparency due to its oxygen vacancies. When doped with fluorine, the material Fluorine Doped Tin Oxide (FTO) exhibits well visible transparency. Also, FTO is mechanically, chemically and electrochemically stable.

Fluorine Doped Tin Oxide Powder FAQs
Q1. How is FTO Powder produced?
FTO Powder is typically produced through methods such as chemical vapor deposition (CVD), sol-gel processes, or spray pyrolysis, where tin precursors are doped with fluorine sources.
Q2. How does the fluorine doping improve tin oxide?
Fluorine atoms introduce free electrons into the tin oxide lattice, significantly increasing its electrical conductivity while maintaining its transparency.
Q3. Can FTO Powder be used in all types of solar cells?
FTO Powder is particularly useful in thin-film and certain other types of solar cells as a transparent conductive electrode. Its suitability may vary depending on the specific type of solar cell and its design requirements.
Q4. What is the difference between FTO and ITO (Indium Tin Oxide)?
Both FTO and ITO are transparent conductive oxides, but ITO is made from indium oxide doped with tin. FTO uses tin oxide doped with fluorine. ITO typically offers higher conductivity and transparency but is more expensive due to the cost of indium.
