The abbreviation TOPCon stands for Tunnel Oxide Passivated Contact. N-type TOPCon solar cells offer numerous advantages over PERC solar cells, such as lower degradation and higher efficiency.
We have further developed the sputtering technologies that have proven themselves many times in VON ARDENNE systems for the mass production of heterojunction solar cells.
As a result, we can also offer coating systems with a capacity of up to 1.2 gigawatts for customers in the TOPCon market, and with the same productivity .
The sputtering process allows the single-sided, full-surface coating of the solar cell rear side with tunnel oxide and a doped amorphous silicon layer in a highly productive inline process. The result is a significantly higher yield than with conventional PECVD and LPCVD processes.
