Frequently Asked Questions
What is the difference between FTO and ITO glass?
FTO (fluorine-doped tin oxide) keeps its conductivity after high-temperature processing, such as sintering TiO2 layers at about 500 °C for dye-sensitized and perovskite solar cells. ITO has lower sheet resistance and a smoother surface, but its resistance rises when heated above about 300 °C in air.
What does ohm per square (Ohm/sq) mean?
It is the sheet resistance of the coating. A lower value means a more conductive coating, which is usually thicker and lets slightly less light through.
What do TEC 7, TEC 8 and TEC 15 mean?
They are grade names for FTO-coated glass. The number roughly matches the sheet resistance in Ohm/sq, so TEC 7 is more conductive than TEC 15.
What is FTO glass used for?
Common uses are dye-sensitized and perovskite solar cells, photoelectrochemical water splitting, electrochromic devices and transparent working electrodes for electrochemistry.
How do I find the coated side and clean the glass?
Touch both sides with multimeter probes: only the coated side conducts. A typical clean is ultrasonic washing in detergent, deionized water, acetone and isopropanol, then UV-ozone or plasma treatment just before deposition.
