OCI to ramp up polysilicon output

South Korea's OCI will start raising polysilicon output from next month, after postponing its capacity expansion plans last summer.

An additional 10,000 tonnes of capacity is set to enter production by the third quarter.

The Seoul-based company expects the polysilicon market to “grow steadily,” as current demand is set to surpass its annual supply of 42,000 tonnes per year, a spokesperson tells Recharge.

Last August, OCI said it would delay a 116.5bn won ($103.8m) plan to expand polysilicon production at its factory in the city of Gunsan due to uncertain business conditions.

OCI is one of the world’s biggest suppliers of polysilicon, a key raw material for the PV industry.
