By [Elliot Clark](https://energytheory.com/author/elliot_clark/)November 17, 20232 Mins Read ![What is a Silicon Boule](https://energytheory.com/wp-content/uploads/2023/02/What-is-a-Silicon-Boule-1024x683.jpg "What is a Silicon Boule?") A silicon boule is a **synthetic, sausage-shaped single-crystal mass** that is tugged and rotated at a rate necessary to preserve the single-crystal structure throughout growth. The Czochralski method is the one that is most frequently used to make boules. ### **What is the Use of Silicon Boule?** Since silicon makes up more than 25% of the earth’s crust, it is the most common solid element on the planet. But it seldom ever appears in its elemental form; almost all of it exists in compounds. Silicon boules, polycrystalline formations with the atomic structure of a single crystal, are **used to create solar cells**. The [ Czochralski method](https://www.pvatepla-cgs.com/en/technologies/czochralski-process-cz/) is the one that is most frequently used to make boules. A silicon seed crystal is submerged in molten polycrystalline silicon during this procedure. A silicon ingot or “boule” is created as the seed crystal is removed and rotated. Given that contaminants often stay in the liquid, the ingot that was withdrawn is unusually pure. Using a circular saw whose inner diameter slices into the rod, **silicon wafers are cut** from the boule one at a time, or many at once, using a multiwire saw. (A diamond saw creates slices that are 5 millimeters thick and as wide as the wafer.) If the wafer is subsequently cut into a rectangular or hexagonal shape, additional silicon is lost from the boule to the completed circular wafer. Because they can be completely fitted together, rectangular or hexagonal wafers are occasionally utilized in solar cells to maximize the utilization of the front surface. The wafers are then prepared in accordance with the system makers’ specifications for cutting, cleaning, and coating. **Must Read**: [ 6 Best Roof Material For Solar Panels](https://energytheory.com/6-best-roof-material-for-solar-panels/) Share.
