The solar cells lining solar panels contain p-n junctions made of polysilicon: The electrons flow through the cell's p-n junction, generating usable electricity! So in essence, the irregular surface and conductive properties of it make it efficient at trapping sunlight and converting photons into harvestable solar energy.
The type used in microchips - called electronics-grade polysilicon - contains some impurities. But solar cells require more pure hyper-refined polysilicon containing virtually no contaminants which can hamper efficiency. Producing ultra-pure polysilicon suitable for solar panels is highly complex, requiring state-of-the-art manufacturing setups.
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.

This resulting "solar-grade polysilicon" or "9N polysilicon" represents one of humanity's most sophisticated and valuable materials. It's essential for fabricating high-efficiency solar cells to enable competitive renewable energy. Global solar demand is estimated to grow over 25% annually this decade as green energy goes mainstream.
Solar PV cells are primarily manufactured from silicon, one of the most abundant materials on Earth. Silicon is found in sand and quartz. To make solar cells, high purity silicon is needed. The silicon is refined through multiple steps to reach 99.9999% purity. This hyper-purified silicon is known as solar grade silicon.
Photovoltaic Energy Polycrystalline silicon plays a crucial role in solar energy production, particularly in the manufacturing of photovoltaic (PV) cells. There are two main types of photovoltaic panels: Monocrystalline panels – Made from single-crystal silicon, offering higher efficiency.
