Indian producer Gautam Photo voltaic has added 500 MW to its TOPCon module manufacturing line, bringing its complete panel manufacturing capability to 1 GW. The road will begin operations in September.

Gautam Photo voltaic will buy TOPCon’s absolutely automated, n-type manufacturing line from Jinchen. The provision deal between the 2 firms was signed at SNEC, sixteenth Worldwide Photovoltaic Energy Era and Good Power Convention and Exhibition.

TOPCon is a complicated photo voltaic module manufacturing know-how. It has a skinny tunneling oxide layer on an n-type silicon substrate, adopted by a layer of extremely doped polysilicon and passivated contacts. The tunnel oxide layer permits cost carriers to go via with minimal recombination loss, whereas passivated contacts scale back floor recombination. This know-how improves photo voltaic module effectivity and reduces panel degradation over time.

N-type TOPCon cells produce as much as 30% extra power than conventionally used p-type PERC cells.
