Polysilicon
OCI is the global player supplying the ultra high purity Polysilicon for solar power generation and semiconductors.
Product Features

Polysilicon
Usage
Polysilicon is the basic core material for Solar PV industry, positioned at the very first step of the PV value chain(ingots wafers cells modules solar power generation systems). OCI provides 10-Nine (99.99999999% purity) Polysilicon for solar power generation and 11-Nine (99.999999999% purity) for semiconductor wafers.
Production Process
Metal Silicon(MG-Si) is produced by reducing and melting quartz. Metal silicon is then mixed with hydrogen and hydrochloric acid to produce high-purity trichloride silane (TCS). Then it undergoes chemical evaporation at high temperatures to produce high-purity solid polysilicon.

In 2008, OCI succeeded in commercial production of polysilicon, which was manufactured only by a small number of European, American, and Japanese companies, and continued to increase solar grade production capacity through expansion. Our Gunsan plant in Korea exclusively produces electronic-grade polysilicon with an annual capacity of 4,700 metric tons. Our Sarawak plant in Malaysia produces solar-grade polysilicon with an annual capacity of 35,000 metric tons.
