6 FAQs about [How to use polysilicon solar panels]
Why do solar panels need polysilicon?
The smartphone, notebook or desktop computer you are using right now needs it; the car you drive needs it; and over 90% of all solar panels producing electricity from the sun need it, too: Polysilicon, the purified variant of the grey silicon metal made of quartz, is indispensable for semiconductor devices and solar cells alike.
What is polysilicon used for?
Here is a primer. Polysilicon, a high-purity form of silicon, is a key raw material in the solar photovoltaic (PV) supply chain. 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.

Why is polysilicon used as a feedstock for solar PV cells?
Owing to its excellent semiconductor properties, polysilicon is used as feedstock for solar, and is the initial building block for manufacturing silicon based Solar PV cells. Due to its semiconductor properties, polysilicon is used as feedstock for solar, and is the initial building block for manufacturing silicon based Solar PV cells.
What is a polysilicon based solar cell?
A pretty good video on polysilicon manufacturing process by Wacker Summary: Polysilicon, a highly refined form of silicon, is the starting material for solar cells. For silicon-based solar cells, polysilicon is the starting material.
What is the purity of polysilicon used for solar cells?
The purity of polysilicon used for solar cells is very high, about 99.999% or higher! The pure polysilicon thus formed is first converted into ingots (a solid, brick-like material). These ingots are further cut into thin wafers by specially designed saws. The wafers are then fabricated into solar cells. Questions from the curious cat
Is polysilicon a good material for IC circuits?
Yes, it is. But the purity of polysilicon required for IC circuits is much higher (99.999999%) when compared to that used for solar cells, for which it is a measly 99.9999% pure! Can anyone set up a polysilicon manufacturing plant?
