ITO Coated Glass Slides Properties and Details

ITO COATED GLASS (Indium tin oxide coated glass) belongs to the group of TCO (transparent conducting oxide) conductive glasses. An ITO glass has a property of low sheet resistance and high transmittance. It is mostly used in research and development. ITO coated glass substrates are widely used to organic/inorganic heterojunction solar cells, Schottky solar cells, CdTe solar cells and other various thin film solar cells as transparent semiconductor oxide electrode materials since their transparency and high conductivity.

The Indium tin oxide coated glass is one of the types of transparent conductive oxide (TCO) coated substrates. It is commonly known as ITO coated glass. The ITO coated glass having excellent conductive and high transmittance properties. The ITO glass is an N-type semiconductor. The chemical formula of Indium tin oxide is Sn:In2O3. The uniform thin layer of Indium tin oxide (ITO) over a glass substrate makes it highly transparent and low surface resistance. The ITO coating over a glass sheet is carried out in the entirely vacuumed condition by magnetron sputtering method at around 300 degree C. It is a single side coating, where coated surface is conductive, and another surface is insulated. In this approach, there is passivation layer of silicon dioxide (SiO2) in between ITO layer and borosilicate glass surface. The standard thickness of SiO2 is 25 nm. The passivation layer is essential to increase the quality as well as longevity of ITO coated glass plate. The borosilicate glass or float glass is a single side finished substrate. The maximum operating temperature of ITO coated glass slide is 350 degree Celsius (i.e. 662 0Fahrenheit).

Customers can choose coating thickness based on coating resistivity required for the job. If you want we can assist via mail or suggest you refer coating thickness versus resistivity chart to ease the decision.

Design of ITO Coated Glass Slides

The ITO coated glass plate is laser cut majorly in square and rectangular shape, sometimes it customized in circular shape also. It is also called as ITO coated glass coverslip. The square shaped standard ITO coated glass slides size is 25mm, 50mm, 100mm, and 200mm. The rectangular shaped ITO glass slide is 50mm x 25mm and 75mm x 25mm. The maximum produced size of ITO coated glass substrate is 405mm x 305mm. The standard thickness of float glass which conventionally used for coating is 0.5mm, 0.7mm, and 1.1mm. The Indium Tin Oxide conductivity depends on the surface resistance, which is reciprocal to conductivity. The specified surface resistivity of the ITO coated glass sheet is in the range of 10 ohms/sq. to 100 ohms per square. The transmittance of the Indium Tin Oxide (ITO) glass coverslips at 550nm are greater than 85%. The ITO film or layer thickness is in the range of 50nm to 200nm (i.e. 500Å – 2000Å). The surface roughness is 1-10 nm depending on their specifications, whereas the ITO work function is 4.8~4.9eV after a proper cleaning. It is also known as ITO wafer. The haze of the conductive glasses is less than 1%.

Customization and Specifications

We can also customized size and specifications of the product as per buyer requirement. The Indium Tin Oxide coated over a polished and unpolished float glass as well as OLED soda lime substrate. The ITO conductive film provides over a quartz and Corning glass substrate. In some instances, double side coated slide can also manufacture. It majorly used in the research laboratories, educational institutes, and industries. In research, it widely utilized for the fabrication of Dye-Sensitized solar cell or organic cells. It is also majorly used for Indium tin oxide touch screen. We also offer a cost effective solutions for many applications based on the bulk requirement. We also provide ITO patterning of the substrate as per ordered designs. The laser and wet etching use for the details patterning develop by Photolithography method. The direct soldering is not possible over an ITO thin film, hence there is a use of conductive paste, conductive ink or copper foil conductive adhesive tape. The ITO coated glass storage temperature is less than 20 degree centigrade for a better life and results.

How to Clean the Glass Slides

We package ITO coverslips very carefully in a special protective packaging to ensure it reaches you clean and without slightest damage. However, there are clients who prefer to clean the glass once it arrives before putting it to use. For all such cleaning purposes, we recommend clearing it with high-quality lint-free cotton dipped in the solvent called the isopropyl alcohol. Clients are warned not to wipe coatings with alkali. Dilute sodium hydroxide solutions are commonly used for patterning ITO. If you use acid of any kind it will cause irreversible damage ITO coating on the glass surface.
We also have Premium order options where customers can place an order for anti-reflective or Index Matching Coatings to increase transmittance on the coating.
