Renewable Energy & Energy Solutions

From the key materials of solar PV projects to solar PV projects,
OCI Holdings envisions a better future with sustainable technology.

Solar-grade Polysilicon

Polysilicon is a core material at the front of the solar PV value chain leading to solar PV projects consisting of ingots, wafers, cells, modules, etc.
OCI produces ultrapure polysilicon of 10-Nines grade (99.999999999% purity) for solar solar PV Projects projects.

In 2008, OCI succeeded in the commercial production of polysilicon, which had only been possible in a few companies in Europe, United States and Japan. Currently, the affiliate OCIMSB produces solar PV polysilicon with an annual capacity of 35,000MT, and plans to increase the capacity by 30,000MT in five years.
