High-Efficiency PV Products

We know how to build high-efficiency PV products. In fact, we are a company founded with the cell customer in mind. Over 15 million cells have been produced from our silicon through 2012, with several million made in-house during a phase in which we operated a PV cell processing line. This accumulated experience, along with our world-class R&D team, ensured our solar silicon product is well-suited to deliver high-efficiency PV products.

Our product can be dropped into conventional ingot, wafer, and cell processing lines with minimal additional preparation compared to electronic-grade silicon. Cells and modules made from our solar silicon product have the following electrical characteristics:

• Cell efficiency with averages over 16.5%. Champion cells have been made in excess of 18%
• Improved low-light performance over conventional electronic-grade silicon
• Module certification from UL and TÜV Rheinland
• Resistivity levels that enable assembly into 60- or 72-cell modules

	We maintain several test sites for modules made from our silicon. The National Renewable Energy Laboratory has several modules for testing at its Colorado headquarters.
	An outdoor test facility in Sunnyvale, California has delivered better-than-expected performance since 2010
