Innovalight Reaches 18% Efficiency with Silicon Ink Solar Cell

Innovalight Inc. said this week that it has demonstrated a record 18% conversion efficiency with silicon-ink processed solar cells. The industry standard size solar cell results were independently certified by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and The Fraunhofer Institute for Solar Energy Systems (ISE) in Germany.

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 percent.

“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 said that its proprietary silicon ink and processing technologies allow crystalline silicon solar cell manufacturers to boost output capacity, solar cell performance as well as reduce costs with a simplified additional step to already installed manufacturing lines. Crystalline silicon solar cell technology accounts for 86% of the commercial solar panel market today, according to Paula Mints, principal analyst for Navigant Consulting Inc.
