ANTI REFLECTIVE COATING

BTUs TCD Series furnaces have been optimized for the deposition of TiO2 anti-reflective coating. This is accomplished by the use of the Atmospheric Chemical Vapor Deposition (APCVD) process. The system is available in 1 or 2 head configurations depending on throughput requirements.

DIFFUSION 

Solar Cell Panels

Anti-reflective thin film coating is required in the manufacture of solar cells to aide in the entrapment of light into the cell. It is typically applied by the atmospheric pressure chemical deposition process (APCVD) using titanium oxide (TiO2) or plasma enhanced chemical vapor deposition (PECVD) using silicon nitride. BTU offers its TCD furnace for the application of anti-reflective coating which is the APCVD process. This is an in-line solution.
