Why Silicon?

It is our belief that in order to make a meaningful contribution to the world’s energy and environmental needs, it is essential to construct solar cells out of abundantly available raw materials that are proven safe.

Fortunately for us, we have silicon with a high efficiency potential.

ABUNDANT
After oxygen, Silicon (Si) is the most abundant element in the Earth’s crust, making up for 25.7% (257,000 ppm) by mass.

Although there are some non-silicon solar cells available, they invariably make use of rare and heavy metals, such as Tellurium (Te) with an abundance similar to Platinum (0.001 ppm) or Indium (In), an important raw material for liquid crystal displays, which, with 0.1 ppm, is about as abundant as silver.

SAFE
Silicon is a non-toxic, safe, proven material that lasts.

Silicon is the foundation of numerous commercial products such as computer chips, glass, steel, cement and lubricants, as well is in consumables such as toothpaste and ketchup.

Silicon is everywhere.

POWERFUL
Silicon is one of the most powerful semiconducting materials. Silicon cells have proven efficiencies above 23% in manufacturing, with theoretical potential of approximately 30%.
