[font size=4]New method for making silicon wafers enables 1366 Technologies to survive and expand.[/font]
By Richard Martin on October 14, 2015
[font size=3]Solar wafer maker 1366 Technologies has survived the carnage in the U.S. solar manufacturing industry over the last five years. Now the company, which uses a novel technology for making the silicon wafers used in most solar cells, is embarking on its next phase, building a large manufacturing plant in upstate New York (see Solar Survivor).
Founded by MIT professor Ely Sachs in 2008, the startup said last week that it will build its first commercial-scale factory in Genesee County, near Rochester. The plant will cost around $100 million and will initially produce about 50 million wafers annually, equivalent to 250 megawatts of power-generation capacity. Eventually, says CEO Frank van Mierlo, 1366 (which is named for the solar constant, the amount of solar energy that reaches Earth, in watts per square meter) hopes to reach three gigawatts of annual production at the Genesee plant, supplying silicon wafers to a solar industry thats growing rapidly in North America, Europe, and the developing world. The Massachusetts-based company says it was lured to New York, as opposed to building in China, through a combination of state incentives, access to cheap hydro power, and the desire to make its products in the United States.
The booming market for residential solar and the rising demand from developing countries including India, which has committed to building 100 gigawatts of solar capacity in the next seven years, is driving a comeback for solar manufacturing in the U.S. (see Indias Energy Crisis). SolarCitys planned factory, also being built in upstate New York, will have a gigawatt of production capacity when fully operational at the beginning of 2017 (see Paying for Solar Power). Last month, the U.S. unit of China-based Seraphim Solar Manufacturing said it will open a new solar factory in Jackson, Mississippi, that will reach one gigawatt of capacity by 2018. In Hillsboro, Oregon, SolarWorld Americas is spending $10 million to expand its factory, currently the largest solar PV production facility in the Western Hemisphere.
Conventional factories produce silicon wafers via a multistep process of sawing, polishing, and slicing that wastes close to half of the silicon. Led by Sachs, who stepped aside as the companys chief technology officer earlier this year, 1366s team of several dozen engineers devised a way to make wafers directly from molten silicon, producing wafers for half the cost of traditional methods and dramatically reducing the amount of wasted silicon. The 1366 process also uses one-third the energy to produce each wafer. While the concept of producing wafers from molten silicon is not original to 1366, the company is the first to develop a production technology that can be expanded to commercial scale.

(38,310 posts)1. I'm curious about how the process actually works.
Proprietary stuff is maddening sometimes.
Best summary I found was: "A thin sheet of silicon freezes inside the direct wafer furnace and is then removed and laser-trimmed to size."
