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, these are TEC 8 (2.2mm thick glass), TEC 10 (1.1mm/3.2mm thick glass), and TEC 15 (2.2mm thick glass); each offer different conductivities and surface roughness, that suit a variety of applications. For patterning of the FTO we recommend the use of Ossila’s simple chemical resistant stickers to allow for the fabrication of 8 pixel devices. 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.

FTO Processing Guide

FTO Coated Glass Etching

For etching of the FTO coated glass you will need the following products: Tec 7/Tec 10/ Tec 15 FTO glass, 8 Pixel Etch Resistant Stickers, Zinc Powder, Hydrochloric Acid, Cotton Buds, and Multimeter. The following is a step-by-step guide for the etching of FTO coatings, this can be downloaded as a PDF; in addition an instructional video is provided. 

  • Prepare a 2M HCl solution

  • Place the 8 Pixel Etch Resistant Stickers onto the FTO glass substrate.

  • Coat the FTO glass substrate in a layer of Zinc Powder.

  • Cover the remaining Zinc Powder with the 2M HCl solution and wait for the reaction to finish.

  • Using a cotton bud firmly wipe away the etched area of the substrate and rinse with DI water.

  • Using a multimeter check the resistance across the etched area, this should be in excess of MOhms. If not repeat the etching steps again.

 

 

FTO Coated Glass Cleaning

For cleaning of the FTO coated glass after etching you will need the following products: FTO glass, 1.1mm Substrate Rack/2.2mm Substrate Rack (product coming soon), Hellmanex iii, isopropyl alcohol, and UV Ozone Cleaner. The following is a step-by-step guide for cleaning FTO coated glass, this can be downloaded as a PDF; in addition an instructional video is provided.

  • Sonicate etched FTO Glass for 5 minutes in hot (70°C) DI water with the addition of 1% Hellmanex.

  • Dump-rinse twice in boiling DI water.

  • Sonicate etched FTO Glass for 5 minutes in Isopropyl alcohol.

  • Dump-rinse twice in boiling DI water.

  • Dry etched FTO Glass using filtered compressed gas.

  • Place the etched FTO Glass into the UV Ozone cleaner and leave for 10 minutes.
