Innovalight Achieves Record Efficiency Silicon Ink Solar Cell

September 09, 2009 by Jeff Shepard

Innovalight, Inc. announced that the company has demonstrated what it claims is a record 18% conversion efficiency with silicon-ink processed solar cells. The industry standard size solar cell results were independently certified by two of the world’s recognized solar cell testing centers, the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and The Fraunhofer Institute for Solar Energy Systems (ISE) in Germany.

Innovalight states that its proprietary silicon ink and processing technologies allow crystalline silicon solar cell manufacturers to dramatically boost output capacity, solar cell performance as well as reduce costs with a simplified additional step to already installed manufacturing lines.

"Recently, NREL verified 18% efficiency which is a very significant achievement," said Martha Symko-Davies, Senior Program Manager at NREL. "We also are pleased that Innovalight has recently been awarded a $3 million Technology Incubator subcontract through the National Renewable Energy Laboratory, funded under the Department of Energy."

"Innovalight’s silicon ink and processing technologies provide a compelling solution in an otherwise undifferentiated marketplace for solar cells," said Homer Antoniadis, Chief Technology Officer for Innovalight. "Optimized for use with industry standard deposition tools, Innovalight’s solution improves the economics of solar cell manufacturing."

Innovalight is currently working with a number of solar cell manufacturing companies and is ramping production of silicon ink at its site in Sunnyvale, California. The company is developing technologies based on silicon ink to ultimately bring conversion efficiencies of crystalline silicon solar cells to over 20%.
