Ultrasonic Spray Pyrolysis for Depositing TCO

Ultrasonic spray pyrolysis equipment for depositing TCO chemistries.

Uniform thin film Indium Tin Oxide (ITO), Aluminum Doped Zinc Oxide (AZO), Zinc Oxide (ZnO), and Fluorine Doped Oxide layers are often created using an ultrasonic spray pyrolysis technique. This unique process demands specialized coating equipment to create necessary coating thickness and morphology, spraying corrosive solutions in a high temperature environment.

In a high temperature ultrasonic spray pyrolysis process, precursor solutions such as Aluminum Zinc Oxide are sprayed onto a substrate heated to approximately 300-500 degrees Celsius. The solvent is evaporated in transit and the ZnO crystalline film is grown on the substrate surface, often soda-lime or other glass. Substrate temperature often dictates the morphology characteristics of the film.
