FTO-coated Glass Description
Conductive glass is a type of glass that exhibits low electrical resistance and low electrical conductivity. It is classified into volumetrically conductive glass and surface conductive glass. The constituent materials of volumetrically conductive glass include alkali oxides, silicon dioxide and titanium oxide.
FTO-coated glass was developed as a substitute for conductive ITO glass. It is employed in liquid crystal displays, photocatalysis, thin-film solar cell substrates, dye-sensitised solar cells and electrochromic glass. Given its ability to withstand high temperatures, FTO-coated glass is used as the transparent electrode material in Perovskite solar cells.
