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.
Ossila supply three types of FTO-coated glass for sale: TEC 8 (2.2mm thick glass), TEC 10 (1mm/3.2mm thick glass), and TEC 15 (2.1/2.2mm thick glass). Each offer different conductivities and surface roughness to suit a variety of applications.
- TEC 8 FTO offers the highest conductivity for applications where low series resistances are crucial.
- TEC 10 FTO offers both high conductivity and high surface uniformity where both properties are crucial for the fabrication of high performance electronic devices.
- TEC 15 FTO offers the highest surface uniformity for applications where thin films are to be used.
Specifications and data files for Ossila’s range of FTO-coated glass can be seen below, along with processing guides for the etching and cleaning of the FTO coating.
