FTO (Fluorine doped Tin Oxide) Glass is one of the most widely used Transparent Conducting Oxide (TCO) coated substrates in photo-electrochemistry. The substrate of 25 mm x 25 mm is a default size for most of redox.me photo-electrochemical cells.

Application note
FTO glass slides are typically used in photo-electrochemistry wherever a glass with an electrically conductive surface and high optical transparency is required, including:

• current collectors in photo-catalysis (e.g. Dye Sensitized Solar Cells (DSSCs), water-splitting, photo-electrochemical sensors)
• wastewater treatment
• spectro-electrochemical devices such as electrochromic displays and windows
• electrodes in (opto-)electrochemical (bio-)sensors, etc.
