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.
