FTO Conductive Glass 10 Ω/sq 350 nm 3.2 mm

The FTO conductive glass substrate requires careful handling and storage to maintain its optical and electrical properties. The SnO₂:F coating is chemically stable but sensitive to moisture and mechanical damage.

• Storage Humidity Limit: Maintain ambient humidity below 65% during long-term storage to prevent degradation of sheet resistance and optical transmittance.
• Light Exposure Restriction: Store substrates in a dry, shaded location away from direct sunlight to avoid UV-induced degradation of the conductive coating.
• Handling Procedure: Handle substrates only by the four edges and never touch the conductive coated surface to prevent contamination and scratches.
• Conductive Surface Identification: The blue film-laminated side indicates the conductive surface; verify orientation before any processing or experimental use.
• CNC Processing Tolerance: When specifying custom CNC processing, provide detailed dimensional drawings with tolerance requirements to ensure cutting precision of ≤0.05 mm.

Follow these steps to safely handle and store FTO substrates without damaging the conductive coating. Proper handling preserves sheet resistance and optical transmittance for experimental reproducibility.

Required Equipment: CNC cutter

1. Inspect the protective film
   Inspect the blue protective film to confirm the conductive surface side and ensure the film is intact before handling.
2. Handle by edges only
   Handle substrates by the four edges only, avoiding any contact with the coated surface to prevent scratches and contamination.
3. Store in controlled environment
   Store substrates in a dry, shaded location with ambient humidity below 65% and away from direct sunlight to maintain performance.
4. Specify CNC dimensions
   Provide detailed dimensional drawings with tolerance requirements when ordering custom CNC processing to ensure ≤0.05 mm precision.

This FTO conductive glass (10 Ω/sq, 3.2 mm substrate, 350 nm SnO₂:F coating) is evaluated for high-temperature photoelectrochemical and dye-sensitized solar cell applications, where its 600°C thermal stability and acid-resistant coating provide a clear advantage over ITO, though post-sintering surface flatness changes and strict humidity-controlled storage requirements impose operational constraints.

Positive

• 600°C thermal stability enables high-temperature sintering: The SnO₂:F coating remains stable up to 600°C, allowing direct sintering of mesoporous TiO₂ layers in dye-sensitized solar cell fabrication without the degradation seen in ITO above 300°C.
• Superior acid corrosion resistance for acidic electrolytes: The fluorine-doped tin oxide coating exhibits outstanding room-temperature resistance to acid corrosion, making it suitable for photoelectrochemical experiments involving acidic electrolytes that would etch ITO coatings.

Trade-offs

• Post-sintering surface flatness variation: Surface flatness increases from pre-sinter values of 1.225 μm / 9.287 μm to post-sinter values of 3.375 μm / 11.225 μm, which must be accounted for in device architectures requiring precise layer thickness control after thermal processing.
• Humidity-sensitive storage requirements: Long-term storage requires ambient humidity below 65% in a dry, shaded location away from direct sunlight to prevent degradation of sheet resistance and optical transmittance.
