What is polysilicon?
You may already know that silicon (Si) is a common element in nature. At HSC, we take this raw material and turn it into something very special. We call it hyper-pure polysilicon.

Why is polysilicon important?
If you have a smartphone or a laptop computer, it’s powered by semiconductor microchips. What makes a microchip work? Polysilicon! In fact, the hyper-pure polysilicon made right here at HSC can be found in billions of electronic devices around the world – maybe even yours!
That’s not all. Polysilicon is the key ingredient that helps solar panels convert sunlight into electricity. Solar energy is one of the cleanest ways to generate electricity because it doesn’t release any carbon dioxide (CO2) – also known as “greenhouse gas” – into the atmosphere.
That’s why the world is making a big transition from fossil fuels to renewable energy sources like solar.
At HSC, we’re leading the way toward a more sustainable, clean energy future – and so can you!
What is Hyper-Pure polysilicon?
What do we mean by “hyper-pure”? Imagine an Olympic swimming pool. Let’s put one grain of sand in that pool. Now imagine just one grain of sand in SIXTEEN swimming pools.
Do you think you could find that one grain of sand? That’s how hard it is to find a flaw in our polysilicon. And that’s why our polysilicon is the purest human-made substance on Earth!
