Full Description of Azo Coated Glass
AZO (Aluminum Doped Zinc Oxide) is amongst the best and most preferred transparent conductive oxide materials owing to its superior optical and electrical properties as mentioned above. Use of AZO-coated glasses is on the rise as the transparent conductive substrate is used in applications like the thin-film solar cell, OLED, electrochromic glass etc. They are used in a wide range of applications like flat panel display electrodes and gas sensors etc.
Owing to their large piezoelectric constant, these films can be used as surface acoustic wave devices and solar cells. Their optical band gap (3.3 eV) is wide which enables transmission of most of the useful solar radiation.
Al Doped ZnO coated glasses supplied by us come with a surface resistance of 10ohm/sq., transmittance >=80%, having a polished surface with no pattern. They have high density, 95+%, they’re hot pressed and conductive.
Its rise in demand comes from the major advantage of cost saving. A major cost saving is possible with AZO materials as compared to ITO and other TCOs. It is possible to obtain the complete range of sheet resistance, from < 50 Ω/sq. to M Ω/sq. with AZO by changing deposition thickness and parameters. As substrate heat is not required, it makes AZO ideal for polymer and substrates that are sensitive to temperature. Patterning of films by etching is easier than when compared to ITO films.
