The story of solar electricity from photovoltaics (PV) is a journey from sand to sun to electricity. At each stage of this journey, both science and magic happens. At SunEdison we have been working for over 50 years to perfect the science and multiply the magic.

From Sand to Sun
to Electricity

Let's begin with the sand. Or, to be more precise, the silicon in the sand. Silicon is the basis for most semiconductors, whether they're used in computer chips or solar panels. Neither industry would exist without this essential element.


In order to be useful silicon must be extracted from the sand and purified. Conventional techniques consume massive amounts of energy and potentially introduce impurities into the silicon. So we invented a better way.

Ultra-pure silicon produced in a better way.
Fluidized Bed Reactor Technology

Fluidized Bed Reactor or FBR technology produces ultra-pure silicon more efficiently and economically than conventional techniques. During the FBR process, very small particles of silicon called seeds are suspended in a cloud of gas. Silicon in the gas attaches to the seeds, forming larger and larger beads which eventually drop out of the gas like rain - silicon rain.

Black Silicon

FBR technology creates silicon 99.9999999% pure. And ultra-pure silicon enables more powerful, more efficient solar cells.

But we didn't stop there. Our latest innovation, High Pressure Fluidized Bed Reactor technology, produces pure silicon 10 times more efficiently and with 90% less energy used than competing technologies.

More efficient ingot manufactured in a better way.
The Continuous Czochralski Process

Isolating and purifying the silicon is just the first step in the journey toward making solar cells and ultimately solar panels. We next have to turn the beads of purified silicon into micro-thin, square slices of pure silicon called wafers. Below you can see ultra-pure silicon beads that have been added to a molten batch of silicon used in the Continuous Czochralski Process (CCz Process).

Sun Solar Flare

First, we melt the silicon and add different elements to it, a process called doping. Most solar cells are made from P-type silicon, which typically has been doped with the element boron during the manufacturing process. P-type silicon doesn't produce the optimal solar cell, but conventional processes have difficulty using other dopants, so P-type silicon it is for most manufacturers.

Not SunEdison. Our proprietary Continuous Czochralski or CCz process enables the creation of N-type silicon, doped with the element phosphorus. And solar cells made with N-type silicon typically deliver 20% to 40% greater power and energy than conventional P-type solar cells.

The next step is to create an ingot of solid, purified silicon that can be sliced into the micro-thin wafers needed for solar cells. We form the ingot out of a single crystal, drawn from the pool of molten silicon. This results in a perfect crystalline structure, where all the atoms are precisely aligned for higher efficiency.

SunEdison's CCz process produces these ingots more efficiently and cost effectively than any other technology.

The Perfect Solar Material

The final product is the result of decades of SunEdison know-how and innovation. It is the perfect solar material, ready to be neatly made into solar cells that better harness the power of the sun.
