FTO Coated Glass

Technical Specifications

Description & Working Principle

FTO coated glass (fluorine-doped tin oxide coated glass) is a form of TCO (transparent conducting oxide) conductive material that provides less expensive conductive glass than ITO-coated glass. It is a functional conductive glass product covered with a transparent FTO conductive oxide layer via a physical or chemical bonding method. The FTO coated glass substrate is coated on one side and insulated on the other. This coating is resistant to higher temperatures. It is weather-resistant and thermally stable, resulting in low sheet resistance and high transmission ability.

The highest operational temperature is 450 degrees Celsius. The glass thicknesses employed for the FTO coating are 1.6mm, 2.2mm, and 3.2mm. It has surface resistances of less than 7 ohms, 10 ohms, and 15 ohms. It has been utilized for solar cell research and development, which is less expensive than ITO-coated glass. It is single-sided coated glass with a tetragonal structure and flawless symmetry.

Due to its superior high-temperature endurance, FTO conductive glass has recently emerged as the ideal transparent electrode material for perovskite solar cells. The product provides an environmentally friendly coating method that dramatically decreases material usage, leaves a finer and more uniform coating without leaking, and reduces maintenance significantly. It may give outstanding anti-reflection properties to glass when coated with a very thin, homogeneous, and durable layer while decreasing exhaust gas and energy consumption during the deposition, and the drying time is quick.

Applications of FTO Coated Glass

FTO glass (Fluorine-doped Tin Oxide) is a translucent conductive metal oxide used to make transparent electrodes for thin film photovoltaics. It is also used in organic photovoltaics, silicon cells, cadmium telluride, decolorization solar cells, and hybrid perovskites. FTO glass has various qualities that make it excellent for manufacturing a wide range of optoelectronic devices, including low surface resistance, high optical transmission, scratch and abrasion resistance, thermal stability up to high temperatures, and chemical inertness. Other applications for FTO glass include:

• Electromagnetic interference/radio frequency interference shielding
• Touchscreen displays
• Heated glass
• Anti-static coatings
• Light-emitting diodes

How to Use FTO Coated Glass

1. Etching

The following items are required for etching.

FTO glass, etch-resistant tape, zinc powder, hydrochloric acid, cotton bud, and a multimeter. The procedure for etching FTO coatings is outlined below.

1. Make a 2M HCl solution.
2. On the substrate, apply an etch-resistant tape.
3. Apply a layer of Zinc Powder to the substrate.
4. Wait for the reaction to finish before covering the remaining Zinc Powder.
5. Wipe away the etched region of the substrate with a cotton bud and rinse with DI water.

2. FTO Cleaning process after etching

The following items are required for cleaning the FTO coated glass after etching: FTO slides, substrate rack, isopropyl alcohol, and UV Ozone Cleaner. A step-by-step approach to cleaning the conductive substrate is provided below.

1. Sonicate, the etched FTO, slides for 5 minutes in hot (70°C) DI water with 1% Hellmanex.
2. Rinse twice with boiling DI water.
3. Sonicate the etched FTO Glass in Isopropyl alcohol for 5 minutes.
4. Rinse twice with boiling DI water.
5. Using filtered compressed gas, dry the etched FTO Glass.
6. Put the engraved substrate in the UV Ozone cleaner for 10 minutes.

Safety Measures

1. Do not expose the product to chemicals that can harm it.
2. Researchers must use safety gear to protect themselves while handling the product.

Frequently Asked Questions (FAQ)

Q: What is the typical sheet resistance of FTO coated glass?

A: Our standard range is ~7 to 15 Ω/square, with options for lower or higher values based on design requests.

Q: Can I get patterned FTO coatings (e.g. via etching)?

A: Yes — we support custom pattern etching services. Provide your mask or design when ordering.

Q: Is FTO better than ITO for high-temperature applications?

A: Yes. FTO is more thermally stable at elevated temperatures and is often chosen for high-temperature processing environments, whereas ITO may degrade under such conditions.

Q: What is the maximum operating temperature?

A: The recommended maximum is ~550 °C (due to glass substrate limitations), though under specific conditions, some FTO films may withstand slightly higher temperatures.
