Polysilicon Latest News
The government is working to add 30 gigawatts (GW) of polysilicon manufacturing capacity by 2030 and is working on a subsidy scheme.
About Polysilicon
- Polysilicon, also known as polycrystalline silicon or simply poly-Si, is composed of multiple tiny crystals or grains of silicon.
- It is composed of multiple smaller silicon crystals fused together in a haphazard manner.
- Polysilicon is highly pure and generates almost as much energy as pure mono-crystalline silicon.
- Because of this, polysilicon is crucial to the solar industry as it plays a key part when manufacturing solar cells that are used in solar panels.
- To produce solar modules, polysilicon is melted at high temperatures to form ingots, which are then sliced into wafers and processed into solar cells and solar modules.
- It is also used in the semiconductor industry to manufacture integrated circuits and other electronic components.
- It is produced by purifying metallurgical-grade silicon into a high-purity form.
- There are two main methods to produce high-quality polysilicon that can be used for solar cell manufacturing: the Siemens process and fluidized bed reactor (FBR) technology.
- Global production is highly concentrated. China accounts for the large majority of solar-grade polysilicon output.
