From polysilicon charge to inspected, sorted wafers, engineered around the n-type material that TOPCon, HJT and BC cells require.
Our crystal growth furnaces produce premium silicon ingots for next-generation photovoltaic applications. The proven Czochralski process runs inside a carefully controlled inert atmosphere, delivering high crystal quality, stable production and optimised oxygen concentration, the combination that modern n-type cell manufacturing demands.
Diamond wire cutting transformed the wafer stage. It enables thinner cuts, lower kerf loss and reduced silicon consumption while improving processing efficiency, wafer yield and surface quality, and it cuts wastewater and COD emissions substantially compared with the slurry processes it replaced.
Thin-wafer capability matters more with every generation. HJT and BC routes both benefit from thinner substrates, so we specify wire management, tension control and handling with headroom below current production thickness rather than at it.
HJT is exceptionally sensitive to metallic contamination and surface condition, because the thin intrinsic amorphous silicon passivation layer deposited later cannot compensate for a compromised surface. If HJT is your route, or a possible future route, the wafer cleaning and handling specification has to reflect that from the outset.
Indicative figures for line sizing discussions. Final specification is set during the engineering phase against your product definition and site conditions.
