The Transparent Powerhouse: A Comprehensive Guide to FTO Coated Glass

In the rapidly evolving world of optoelectronics and renewable energy, one material stands as the foundation for innovation: FTO Coated conductive glass. Fluorine-doped Tin Oxide (FTO) coated glass is a functional material that combines two seemingly opposite properties: optical transparency and electrical conductivity.

As a critical component of next-generation technology, choosing the right FTO glass is essential to the success of your research or industrial application.

What is FTO Coated Glass?

FTO glass belongs to the family of TCO (Transparent Conductive Oxide) glasses. Fluorine-doped tin oxide is deposited as a thin layer on a high-quality glass substrate (usually soda-lime or borosilicate glass).

Key Product Details:

• High Thermal Stability: Unlike ITO (Indium Tin Oxide), FTO glass remains stable at high temperatures (up to 600°C), making it ideal for processes involving annealing.
• Low Sheet Resistance: Provides excellent electrical conductivity for efficient electron transport.
• High Transmittance: Maintains high transparency in the visible spectrum (typically >80%).
• Chemical Resistance: Highly resistant to atmospheric conditions and harsh chemicals.

Variations & Capacity

We offer FTO glass in various specifications to meet the needs of both micro-scale lab research and large-scale industrial production.

• Sheet Resistance: Available in ranges from 7 ohms/sq to 100 ohms/sq.
• Thickness Options: Standard glass thicknesses include 1.1mm, 2.2mm, and 3.2mm.
• Surface Roughness: Options for Smooth or Hazy surfaces depending on light-scattering requirements.
• Custom Dimensions: From small 10mm x 10mm slides for testing to large 300mm x 300mm plates for panels.
• Substrate Types: Standard Soda-Lime glass or high-temperature Borosilicate glass.

High-Tech Applications

FTO Coated Glass is the silent hero in several cutting-edge fields:

1. Photovoltaics: The primary electrode for Dye-Sensitized Solar Cells (DSSC) and Perovskite Solar Cells.
2. Electrochromic Devices: Used in Smart Windows that change color or opacity with an electric pulse.
3. Touch Screens: Acts as a transparent conductive layer for displays and sensors.
4. Laboratory Research: Used in electrochemical experiments, heating elements, and as a substrate for thin-film deposition.
5. EMC/EMI Shielding: Used in specialized windows to block electromagnetic interference.

What to Look For when buying FTO Coated glass

When purchasing FTO glass, consider these four technical factors to ensure compatibility with your project:

1. Sheet Resistance vs. Transparency: Generally, a thicker FTO coating leads to lower resistance (better conductivity) but may slightly decrease transparency. Choose the balance that fits your device.
2. Temperature Requirements: If your process involves high-heat annealing (above 300°C), FTO is superior to ITO, as ITO’s conductivity degrades at high temperatures.
3. Surface Haze: For solar cells, a certain level of haze (surface roughness) is often preferred because it scatters light, increasing the photon path length and improving efficiency.
4. Etching Compatibility: Ensure the FTO layer is uniform enough for laser or chemical etching if you need to create specific circuit patterns.
