FTO (fluorine-doped tin oxide) glass is a transparent conductive metal oxide that can be used in the fabrication of transparent electrodes for thin film photovoltaics, such as: organic photovoltaic, amorphous silicon, cadmium telluride, dye-sensitised solar cells, and hybrid perovskites.
FTO glass also has a varied range of other applications, including touch screen displays, electromagnetic interference/radio frequency interference shielding, heated glass, anti-static coatings, and light-emitting diodes. There are several properties of FTO glass that make it suitable for the fabrication of a wide range of optoelectronic devices: these include low surface resistivity, high optical transmittance, scratch and abrasion resistant, thermally stable up to high temperatures, and inert to a wide range of chemicals.
