Polysilicon Overview

Polysilicon is widely used in Integrated Circuit (IC) and

Photovoltaic (PV) industries. It is a major material used

in making semiconductor chips and solar cells. The

semiconductor chips are used for the production of electrical

and electronic devices like computers while the solar cells

are used to manufacture solar panels that convert solar energy

to electricity.

Polysilicon is categorized into two grades: Solar Grade

Silicon (SG) which has a silicon content of 99.9999% and

Electronic Grade Silicon (EG) which has a silicon content of

99.999999999%.

Market demand for polysilicon has increased due to the use of

alternative and more environment-friendly sources of energy.

The production of polysilicon has increased to meet the

market demand.

Polysilicon Manufacturing Process

The process of manufacturing polysilicon starts with rening

its raw material, silica. Silica, found in sand and quartz,

is reduced to remove impurities and then purified to

produce Metallurgical-Grade Silicon (MGS). The metallic

silicon is processed using either the Siemens reactor or

Fluidized Bed reactor. Both processes use Trichlorosilane

(TCS) undergoing further chemical or physical processes to

produce polysilicon.
