Thin Film Solar Cell Coatings
Ultrasonic spraying technology is regarded as an effective thin-film coating preparation process, which can be used for the preparation of various functional layers in thin-film solar cells, such as TCO coating (transparent conductive oxide); AR anti-reflection and anti-reflection film preparation; calcium Preparation of active layers such as titanium ore, quantum dots, buffer layers or organic layers; and spray preparation of transparent conductive film coatings such as CNTs (carbon nanotubes), silver nanowires, and graphene. In the preparation process of the thin-film solar cell functional layer, the ultrasonic spray head and the atomization device can accurately coat the precursor or suspension onto the surface of the substrate.
The cost of the ultrasonic atomization nozzle system is much less than that of CVD and sputtering equipment, which can reduce the cost per watt of manufacturing thin-film solar cells while still providing higher battery efficiency.
Application
